Abstract excerpt

A class V chitinase from Nicotiana tabacum (NtChiV) with amino acid sequence similar to that of Serratia marcescens chitinase B (SmChiB) was expressed in E. coli and purified to homogeneity. When N-acetylglucosamine oligosaccharides [(NAG)(n)] were hydrolyzed by the purified NtChiV, the second glycosidic linkage from the non-reducing end was predominantly hydrolyzed in a manner similar to that of SmChiB. NtChiV...
