Recently the investigation of the structure, molecular dynamics and action mechanism of enzymes revealed that protein globules of many enzymes consist of two tightly packed knots (matrix, domains, blocks) tethered with a relatively flexible spacer. (Lumry, 1995a,b, 2002 and references herein) (See also Section 4.1). The enzyme active sites are most commonly located in a cleft between these domains. Binding of substrates and inhibitors depends on the extend of matrix contraction (Fersht, 1999). 

Figure 9 The orientation of the domains from an arthropod and a functional unit from a molluscan hemocyanin are compared. In the first case (a) F49 in the N-terminal domain blocks the entrance to the active site, in the latter one (b) L2830 located in the C-terminal domain ...

NAD -dependent alcohol dehydrogenases (EC 1.1.1.1) are encoded in the C. elegans genome (Fig. 15.1). The list of standard PEDANT queries includes EC numbers, PROSITE patterns, Pfam domains, BLOCKS, and SCOP domains, as well as PIR keywords and PIR superfamilies. Although PEDANT does not allow the users to enter their own queries, the variety of data available at this Web site makes it a convenient entry point into the held of comparahve genome analysis.

Figure 37 and the scheme presented therein show five <2 levels for glass transition dynamics in PDMS blocks, corresponding presumably to different conformations of chains between rigid domains (blocks) and different distances between PDMS segments and rigid walls. The loosened molecular packing in PDMS blocks... 

Fig. 37 Activation energy Q vs characteristic glass transition temperature (Tg, Tg, T ) dependencies for the PDMS blocks in different types of block copolymers [25,26,128,129]. The hatched zone corresponds to the non-cooperative, Arrhenius relaxations at frequencies of ca. 10 Hz. The numbers 1-5 in the circles indicate the Q levels for cooperative, low-cooperative and non-cooperative segmental motion in PDMS blocks with different conformations and locations between rigid domains blocks), shown schematically below...
