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 (tempera...

Summary: | 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 that this enzyme can be defined as a psychrophilic protease. Inhibitory analysis together with substrate specificity indicates that the studied PSP exhibits properties of serine trypsin-like and Zn-dependent protease. |
