As one of the key amino acid residues, Phe120 was very significant in the selectivity and region-specificity of substrates binding and catalysis in catalytic site of CYP2D6 (Keizers et al.
of the medium, thereby destroying the positive charge on the amino acid residue (see Chart 6).
The open reading frames (ORF) predicted for the Sp-AT1, Sp-AT2, and Sp-AT3 cDNA clones ranged from 442 to 618 amino acid residues, similar to the range found across the eight families of amino acid transporter genes expressed in animals (300-710 residues for these families; Saier, 2000).
Eight structures were found in the precursors of putative oligopeptides after translation of nucleotide sequences to amino acid residue sequences and comparison of their precursors with precursors of known oligopeptides (or with oligopeptides only).
Analyses of the effects of changes at amino acid residues 10 and 17 could not be made, as these positions could not be modeled using either of the template protein structures.
The HA gene of this 2009 virus shares similar amino acid residues in antigenic sites with those of the 1918 virus, which differ in only 10 amino acid residues: S159N in Sa site, G188S and T189A in Sb site, V169I, N171D and K209R in Ca1 site, S140P, Y141H and S145K in Ca2 site, and L75S in Cb site.
The new study demonstrated how a broadly neutralizing HIV antibody called PG9 disarms the virus by grabbing hold of the sugar at residue 160, along with part of a second sugar and a short string of amino acid residues in the V1/V2 region of an HIV spike.
For example, 36th amino acid residue (isoleucine) of HN gene in our study isolate is hydrophobic but it is polar (threonine) in the representative NDVs.
This threshold was then used to identify the 52 species-associated positions at which each of the 2 viruses settles as a distinct amino acid residue that is characteristic of the host.
The method consists of generating a random population of polymerase mutants by mutating at least one amino acid residue of a thermostable polymerase and screening the population for one or more active polymerase mutants by genetic selection.
In this study we computed for every amino acid position (distributed in the 11 known influenza viral ORFs) an entropy value that represents how conserved an amino acid residue is at that given position.
Recently, we mapped the binding site of plectin to vimentin, and to keratinocyte cytokeratins, to a stretch of [approximately]50 amino acid residues within plectin's terminal repeat 5-domain; and a basic amino acid residue cluster within a functional nuclear targeting sequence motif was identified as an essential element of this site (Nikolic et al.
