Abstract:
Four extracellular proteins with chitinase activity capable of binding chitin substrates have been revealed in the culture liquid of chitinase superproducing mutant strain M-1 of Serratia marcescens. Proteins were analyzed by SDS-PAGE and MALDI-TOF mass spectrometry. Based on the data obtained, the proteins were identified as typical chitinases of S. marcescens: ChiA, ChiB, ChiC, and CBP21.
