A class of enzymes that catalyze geometric or structural changes within a molecule to form a single product. The reactions do not involve a net change in the concentrations of compounds other than the substrate and the product.(from Dorland, 28th ed) EC 5.
Isomerase
D007664
Ketosteroids
Steroid derivatives formed by oxidation of a methyl group on the side chain or a methylene group in the ring skeleton to form a ketone.
Oxosteroids
D011549
Pseudomonas
A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants.

Secosteroids
Steroids in which fission of one or more ring structures and concomitant addition of a hydrogen atom at each terminal group has occurred.
D013251
Steroid Isomerases
Enzymes that catalyze the transposition of double bond(s) in a steroid molecule. EC 5.3.3.
