摘要: Abstract A novel penicillin G acylase from the bacterial strain Achromobacter sp. CCM 4824 was characterized. The specific activity of purified enzyme 27.6 U mg −1 protein (6-nitro-3-phenylacetylamidobenzoic acid, NIPAB as substrate). consists two dissimilar subunits α and β with a molecular mass 27.0 62.4 kDa, respectively. isoelectric point about pH 8.8. N-terminal amino acid sequence subunit (SNMWIVGRDHAKDARSILLN) internal (YGYGYAVAQDRLFQMEMAR) exhibited significant similarity acylases. K m values for were 1.9±0.1 4.5±0.2 μM, turnover rates k cat 29±1 19±1 s , maximal hydrolytic found at 7.5 temperature 60 °C. In contrast to published substrate specificities acylases, an almost two-fold ampicillin, amoxicillin cephalexin compared G.
