• enzyme
  • Despite of high sequence identity to previously reported Aspergillus oryzae and Penicilluim oxalicum β-N-acetylhexosaminidases, this enzyme tolerates significantly better substrate modification. (nih.gov)
  • Beta-N-acetylgalactosaminidase (EC 3.2.1.53, N-acetyl-beta-galactosaminidase, N-acetyl-beta-D-galactosaminidase, beta-acetylgalactosaminidase, beta-D-N-acetylgalactosaminidase, N-acetylgalactosaminidase) is an enzyme with systematic name beta-N-acetyl-D-galactosaminide N-acetylgalactosaminohydrolase. (wikipedia.org)
  • This enzyme catalyses the following chemical reaction Hydrolysis of terminal non-reducing N-acetyl-D-galactosamine residues in N-acetyl-beta-D-galactosaminides Frohwein, Y.S. (wikipedia.org)
  • One of the important occurrences of glycoside hydrolases in bacteria is the enzyme beta-galactosidase (LacZ), which is involved in regulation of expression of the lac operon in E. coli. (wikipedia.org)
  • various
  • Differences in primary sequence and the spatial arrangement of these loops and their interplay with active site amino acids, reflected by interaction energies and dynamics, account for the different catalytic activity and substrate specificity of the various fungal and bacterial β-N-acetylhexosaminidases.
