Blautia producta K 2/25.1: 7β-hydroxysteroid dehydrogenaseInferred from experiment

In Pathway: glycocholate metabolism (bacteria)

Note that this reaction equation differs from the official Enzyme Commission reaction equation for this EC number, which can be found here .

The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.
