Characterized a new single modular chitinase, SmChiD from Serratia marcescens GPS5.
Without accessory binding domains SmChiD hydrolyzed polymeric chitin substrates.
SmChiD exhibited chitobiase and transglycosylation activity on chitooligosaccharides.
Transglycosylation activity of SmChiD can be used for synthesis of long chain CHOS.
Chitobiase activity of SmChiD can be used for producing GlcNAc from polymeric chitin.
