Primary structure of triacetinase — An esterase from cotton seeds IV. Peptides of the chymotryptic and thermolytic hydrolysis of cyanogen bromide fragments of triacetinase

Summary 1. Peptides from a chymotryptic hydrolyzate of cyanogen bromide fragment B-7 have been isolated and characterized. The structure of some peptides of the chymotryptic hydrolyzate have been studied and this has enabled the tryptic peptides to be linked up.2. The peptides of a thermolysin hydrolyzate of cyanogen bromide B-5 have been isolated and characterized. The study of the structure of the thermolysin peptides has permitted the linking of two tryptic peptides.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.
