... purines (G and A). Guanosine is affected more than Adenosine and gel bands appear darker on a gel. Hydrazine works for pyrimidines (C and T). Only Cystine bases are cleaved in high salt and are distinguished from Thymine bases. DougB

Re: Peptide binding to MHC molecule

... for serine would be probably OK volume-wise (-H is smaller the -CH2OH) but doesn’t have the possibility for making a hydrogen bond; substituting cystine for serine also is OK sterically (-CH2SH is about the same size as -CH2OH and the sulfur is slightly polar) but sulfur doesn’t make as good ...

Re: Competitive/Non competitive inhibitors

... simply inactivate the enzyme. I know amylase has a number of disulfide bridges, which probably won’t react with Cd, but if there is a crucial free cystine residue, well, you may get inhibition, but exactly what the kinetics will be, I wouldn’t care to predict. Maybe you would get what is called ...
