Descriptions
Analysis Note Also contains clostripain, nonspecific neutral protease, and tryptic activities.
Unit Definition One collagen digestion unit liberates peptides from collagen equivalent in
ninhydrin color to 1.0 μmole of leucine in 5 hr at pH 7.4 at 37 C in the presence of calcium
ions.
One FALGPA hydrolysis unit hydrolyzes 1.0 μmole of furylacryloyl-Leu-Gly-Pro-Ala

One neutral protease unit hydrolyzes casein to produce color equivalent to 1.0 μmole
tyrosine per 5 hr at pH 7.5 at 37 °C.
One clostripain unit hydrolyzes 1.0 μmole of BAEE per min at pH 7.6 at 25 °C in the
presence of DTT.
