Abstract
The same sequence [glu-Ser-Val] is the site of reaction with DFP [di-isopropyl phosphorofluoridate] in phaseolain [the trivial name for the enzyme isolated from Phaseolus vulgaris] as the 3 main peptide bands representing this sequence are evident in the preparations examined. It is likely that the enzyme from brewer'' yeast (Felix Brouillet, 1966) that is inhibited by DFP would have the same sequence about a reactive serine residue as the enzyme in the preparation from baker''s yeast.
