Complete amino acid sequence of endo-beta-N-acetylglucosaminidase from Flavobacterium sp.
The complete amino acid sequence of endo-beta-N-acetylglucosaminidase from Flavobacterium sp. has been determined by analysis of peptides after cleavage with lysyl endopeptidase, pepsin and chymotrypsin. The protein consists of a single polypeptide chain consisting of 267 amino acid residues and a molecular mass of 27972 Da. The sequence of Flavobacterium endo-beta-N-acetylglucosaminidase is very close to that of the Streptomyces enzyme (endo-H), having 60% similarity and very similar hydropathy profiles. Similarities were also found between Flavobacterium endo-beta-N-acetylglucosaminidase and chitinases from Bacillus circulans, Serratia marcescens and Phaseolus vulgaris.
