Isolation and some properties of extracellular amylases from Fusarium martii var. minus f.2

Abstract

α-amylase and glucoamylase were isolated from the liquid culture medium of <i>Fusarium martii</i>. At 10^-3 M concentrations PCMB inhibited the activity of both enzymes, which indicated that they require SH groups for enzymatic activity, α-amylase was also inhibited by DFP at 10^-3 M. One may thus assume that serine is present in the active center of the examined amylase.
