abstract：:Streptomyces caespitosus neutral protease (ScNP) is one of the smallest metalloproteinase with a molecular mass of 14 kDa. Effects of solvent composition on ScNP activity were examined using a peptide substrate. The k(cat)/K(m) values of ScNP exhibited bell-shaped pH-dependence with the optimal pH of 6.4-7.0 and the p...
