This paper reports an insight into the kinetic mechanism of activation
and then inhibition in a thermolysin - catalyzed peptide synthesis of
dipeptide (benzyloxycarbonyl)-L-phenylalanyl-L-phenylalanine methyl e
ster in aqueous - organic one phase system containing n-alcohols as ac
tivator. The jump in catalytic efficiency - as an effect of alcoholic
solvents and the kinetic mode of activation are discussed.
