title: Catalytic mechanism of histone in peptide formation from phenylalanyl adenylate.
abstract: Catalytic action of histone on peptide formation from phenylalanyl adenylate was studied. A peptide bond formation from phenylalanyl adenylate releases two protons. The proton release was increased in the presence of histone at a higher concentration. The catalytic action seems to be due to basic circumstance induced by histone, since (1) basic condition enhanced the proton release; (2) basic amino acid did not enhance the proton release.
