WebThe precursor amino acid lysine contains two amino groups, one at the α-carbon and one at the ε-carbon. Either can be the location of polymerization, resulting in α-polylysine or ε-polylysine. Polylysine is a homopolypeptide belonging to the group of cationic polymers: at pH 7, polylysine contains a positively charged hydrophilic amino group.

Web9 iul. 2012 · Specifically, this study focuses on the following: (1) whether the replacement of arginines with lysines on protein surface can induce more electrostatic interactions in the protein; (2) whether such mutagenesis can stabilize the protein; and (3) what type of stability can be improved by mutagenesis. WebLysine led to an additional blocking effect on proximal tubular uptake of both sa-glyco-Fab and nonglycolated Fab. Addition of furosemide yielded only a small effect when used with lysine. ...

WebThe isoelectric point, pI, is the pH of an aqueous solution of an amino acid (or peptide) at which the molecules on average have no net charge. In other words, the positively … A number of algorithms for estimating isoelectric points of peptides and proteins have been developed. Most of them use Henderson–Hasselbalch equation with different pK values. For instance, within the model proposed by Bjellqvist and co-workers the pK's were determined between closely related immobilines, by focusing the same sample in overlapping pH gradients. Some improvements in the methodology (especially in the determination of the pK values for m…
