Branch specification

Short branches, specifically ethyl branches up to about 2 mol%, are formed in the polymerization of ethylene by meso-ansa zirconocenes containing unsubstituted cyclo-pentadienyl and indenyl ligands [Melillo et al., 2002]. Ethyl branches form by an isomerization process in which the usual P-hydride transfer to monomer is immediately followed by reinsertion of the vinyl-terminated polymer into the formed ethyl-zirconium bond. 

Branch specification Branches are enclosed in nested or stacked parentheses— for example, C(C)CC(N)C(=0)0 for valine.

The potential for loss of the system can then be described by probability Pab (the system fails as soon as both branches fail in reaction to the same stress S(x) generated with demand x, with branch specific strength functions Sa(x) a Sb(x))... 

In summary, using a novel MS-based assay the molecular basis of carbon ( -branch specificity in trans-AT PKSs KS domains has been identified. A key residue has been characterised in the active site of BaeL KS5 which sterically dictates the tolerance for -branched substrates. Examination of this residne in the sequences of 150 KS domains from trans-AT PKSs suggests that the presence of... 

Program points are not restricted to simple addresses. A program point description particularly suited for calls and branches specifications is " R" + n COMPUTED which refers to the nth computed call or branch in routine R. 

The specificity of a colostrum sialyltransferase was investigated by Van den Eijnden et al. (1980) using glycopeptides derived from asialo-aj-acid glycoprotein as substrates. The positional specificity as well as the branch specificity of the enzyme were studied. 

Because of this branch-specific method of process technologies and modularization of products by the use of silicon IP, the semiconductor industry provides a good pattern for customization of products using templates and unified underlying production processes. Some other industries, like the production of printed circuit boards (PCBs) apply this method as weU (Macleod 2002). 

The different lacNAc termini on branched N-linked oligosaccharides are not acted upon at the same rates by all enzymes. The preference of an enzyme for a lacNAc unit on one particular branch has been termed branch specificity . A summary of the branch specificities of four common glycosyltransferases acting on Gal(pi-4)GlcNAcP termini is shown in Figure 8.

The branches to which the enzymes preferentially introduce a sugar residue are indicated by —Note that a3-NeuAcT and p3-GlcNAcT do not show branch specificity with the di-antennary structure.
