ABSTRACT Streptococcus iniae is a pathogenic and zoonotic bacteria that impacted high mortality to many fish species, as well as capable of causing serious disease to humans. Alanine racemase (Alr, EC 5.1.1.1) is a pyridoxal-5′-phosphate (PLP)-containing homodimeric enzyme that catalyzes the racemization of L-alanine and D-alanine. In this study, we purified alanine racemase from the pathogenic strain of S. iniae, determined its biochemical characteristics and inhibitors. The alr gene has an open reading frame (ORF) of 1107 bp, encoding a protein of 369 amino acids, which has a molecular mass of 40 kDa. The optimal enzyme activity occurred at 35°C and a pH of 9.5. -

There are also a number of newly described specific diseases of collagen in both man and domestic animals. Thus, an understanding of the synthesis, deposition, and turnover of collagen is important for the pathologist, the clinician, and the basic scientist alike. -
