WW domains (named after the one letter abbreviation for the amino acid tryptophan) are small regions of around 30 residues, which, like SH3 domains, bind to polyproline sequences. These sequences often contain the consensus sequence PPXY or PPLP. Examples of proteins that contain WW domains include Nedd4 E3 ubiquitin ligase (Fig. 1) and IQGAP1. 

As a consequence, a moving average in the time domain is a multiplication in the Fourier domain, namely ...

To facilitate cross referencing between the names of domain families used in this article and structural, functional, and evolution information available from the literature, the domain names used by the WWW-based resource SMART (http //smart.embl-heidelberg) are shown in bold and in a proportional font. 

A simple example of the first method is to screen requests to ensure that they come from an acceptable (i.e., previously identified) domain name and Internet protocol address. Firewalls may also use more complex rules that analyze the application data to determine if the traffic should be allowed through. For example, the firewall may require user authentication (i.e., use of a password) to access the system. How a firewall determines what traffic to let through depends on which network layer it operates at and how it is configured. Some of the pros and cons of various methods to control traffic flowing in and out of the network are provided in table 9.12. 

There are at least two assembly domains, namely the L20 domain and the L15 domain, in the 50 S assembly map (Fig. 15). Proteins within the L20 domain are essential for the assembly but not for the function of the 50 S subunit whereas those in the L15 domain are functionally important proteins whose assembly occurs at a late state. As with the 30 S subunit, the assembly map of the 50 S subunit (Rohl and Nierhaus, 1982) not only reflects the assembly dependence but also the topographical relationship of the proteins within the ribosomal particle. This conclusion is supported by a good correspondence between the assembly map on the one hand, and results from cross-linking studies and from the sequential removal of proteins from the particle by LiCl on the other hand. There is also a correlation between the interdependence of proteins during the assembly process and the arrangement of their genes on the E. coli chromosome (Rbhl et al., 1982).

In the corrosion example, we defined a layer of material containing oxidation and corrosion products. In this domain named C, for example, two phases were specified to exist, according to some particular model of the process. One of the phases is denoted CuO, and represents an oxide coating that has formed. The second phase, is designated CuS2, and contains products of an atmospheric sulfidation process. Within each phase, different chemical species may reside, for example, Cu+ ions, elemental Cu, holes, and electrons. The list of species depends on the particular reaction mechanism. 

Gelsolin itself was discovered in 1979 by Yin and Stossel based on its ability to activate the gel-sol transformation of actin filaments in a calcium-dependent manner (Yin and Stossel, 1979 Yin et al., 1980). Gelsolin is composed of six domains, named S1-S6, that appears to have arisen from triplication, followed by duplication of an ancestral gene encoding a single domain protein of about 15 kDa (Kwiatkowski et al., 1986) (see Figure 2 Gelsolin structure). 

The WHOIS service searches a database of domain names and provides email addresses, mailing addresses and telephone numbers of people responsible for a particular domain [5]. This information is provided by the Internet Registration service (InterNic). The WHOIS service is accessible by Internet users using telnet, via e-mail, and by the whois command. A limitation of this service is that it only contains information about the top-level domains, but no information about subdomains and individual computers. Moreover there is no cooperation between the distributed WHOIS databases [4],... 

Traceroute is effective for analysis of packets route and for determination of the host domain name. However its application for geographical localization of remote host has some limitations because it is based on determination of the packets route but not determination of destination computer [7]. Therefore in [8] is shown that using the traceroute can give an ambiguous results. 

It is interesting to analyze the geographical location of the attack sources, as we have shown in Section 4.1. Other potentially interesting information can be the machine name resolution. The Domain Name Resolution (DNS) associates one name to one IP. It is based on a distributed database... 

The IP address is generally associated with fully qualified domain name which users recognize and use. The name of a computer can then be < computer >. domain... 

Figure 12.18. Output of Pfam search results. Pfam search is performed with amino acid sequence derived from lipoamide dehydrogenase (Schizosaccharomyces pombe). The table for the trusted matches from Pfam-A for pyr redox (pyridine nucleotide disulfide oxidoreductase) and pyr redox dim (pyridine nucleotide disulfide oxidoreductase, dimerization) domains and their alignments (partial) to HMMs ( ->) are shown. The trusted matches from Pfam-B, the potential matches (Thi4 for thiamine biosynthetic enzyme domain), and the bead-on-a-string sketches are not shown. Select the linked domain name to view the functional description of the domain. The HMM alignments are followed by an option button (Align to seed or Align to family) that enables the user to view/save the multiple alignment of each matched family.

Members of the Bcl-2 family share one or more Bcl-2 homology (BFI) domains, named BFI1, BFI2, BFI3, and BFI4 (Adams and Cory, 1998). It is not yet clear which structural features determine if these proteins possess pro- or anti-apoptotic activities. However, some studies revealed that the BH3 domain is a critical domain for the proapoptotic members (Chittenden et al., 1995). Besides BH domains, some contain a hydrophobic domain in the C-terminal region, which is essential for the attachment to intracellular membranes, like the outer mitochondrial, nuclear, and endoplasmic reticulum membranes (Krajewski et al., 1993 Nguyen et al., 1993). 

Three NH2-terminal D-domains, designated Dl, D2, and D3, are found in all gel-forming mucins whereas a fourth D-domain, named D4, is at the COOH terminus of MUC2, MUC5AC, and MUC5B but not MUC6 and MUC19 (Fig. 2.1) (Perez-Vilar and Hill 1999 Dekker et al. 2002 Chen et al. 2004 Rousseau et al. 2004). A partial D-domain, D , is between D2 and D3 in all of them. Each...
