Psychrophilic trypsin-type protease from Serratia proteamaculans


A preparative method for purification of a novel protease from the psychrotolerant Gram-negative microorganism Serratia proteamaculans (PSP) was developed using affinity chromatography on BPTI-Sepharose. It yielded electrophoretically homogeneous PSP preparation of 60 kD. The PSP properties (temperature and pH stability, high catalytic efficiency) indicate… (More)
