    摘要: A process for the preparation of a purified transaminase having a molecular weight of 20,000 to 250,000 daltons, an isoelectric point at a pH between 3.0 and 8.0, a pH optimum in a range from 5.0 to 10.0 and a substrate specificity for the transamination of (3-carboxy-3-oxo-propyl)-methyl-phosphinic acid or the esters thereof.The production of the enzyme comprises cultivating E. coli ATCC 33849, disrupting the cultivated E. coli ATCC 33849, obtaining a supernatant therefrom containing the enzyme and isolating the transaminase by heating the supernatant at a temperature and for a time sufficient to denature proteins other than the transaminase and than finally removing the denatured proteins from the supernatant.
