The beta-N-acetylglucosaminidase of Escherichia coli was found to have a novel specificity and to be encoded by a gene (nagZ) that maps at 25.1 min. It corresponds to an open reading frame, ycfO, whose predicted amino acid sequence is 57% identical to that of Vibrio furnissii ExoII. NagZ hydrolyzes the beta-1,4 glycosidic bond between N-acetylglucosamine(More)
A tissue‑specific promoter can control downstream gene expression in tissues or organs. The human involucrin (hINV) promoter (pINV) that contains 2474 bp of hINV upstream sequence is able to regulate tissue‑specific gene expression. This tissue specificity may be important for the prevention and treatment of human papilloma virus infections. pINV was cloned(More)
