Abstract: | The gene encoding the periplasmic beta-N-acetylglucosaminidase (GlcNAcase B) from a marine Alteromonas sp. strain, O-7, was cloned and sequenced. The protein sequence of GlcNAcase B revealed a highly significant homology with Vibrio GlcNAcase and alpha- and beta-chains of human beta-hexosaminidase. |
