1. Thirty-eight steroids were tested as substrates for a 7 alpha-hydroxy steroid dehydrogenase preparation from a strain of Escherichia coli; an improved method of making the crude enzyme is described. 2. Steroids having a 7 alpha-hydroxyl group in the molecule were substrates except (a) when the 5 beta-cholan-24-oic acid side chain was shortened to less than four carbon atoms and (b) in certain cases when sulphate ester groups were present in the molecule. 3. For testing with the enzyme, a new specimen of 7 alpha-hydroxy-3,12-dioxo-5 beta-cholan-24-oic acid was made, which had properties different from those previously described.

In Mimosa pudica L. both L- and DL-lysine serve as specific precursors of the -γ-pyridone nucleus of mimosine. Succinic acid is also incorporated into the nucleus. Glycerol and glyceric acid enter the side chain of mimosine. An improved method for the isolation of mimosine from M. pudica is described.
