title: Bacterial 3alpha-hydroxysteroid dehydrogenase is homologous to a fusion of bacterial ribosomal L10 and L7/12 genes.
abstract: 3alpha-Hydroxysteroid dehydrogenase catalyzes the reversible oxidation of 3alpha-hydroxyl groups of the steroid nucleus. Sequence analysis reveals that this enzyme is homologous to ribosomal proteins L10 and L7/12. The alignment suggests that 3alpha-hydroxysteroid dehydrogenase is formed by a fusion of the two ribosomal proteins.
