Abstract excerpt
In a steroid degradation gene cluster of Comamonas testosteroni TA441 consisting of ORF18, 17 and tesIHA2A1DEFG, ORF18 was implicated in encoding a CoA-transferase by database searches, but the matching substrate was not clear. In this study, ORF18 was shown to be necessary for conversion of 9,17-dioxo-1,2,3,4,10,19-hexanorandrostan-5-oic acid, a product of hydrolysis of...
