16-alpha-hydroxyprogesterone dehydratase

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is 16alpha-hydroxyprogesterone hydro-lyase (16,17-didehydroprogesterone-forming). Other names in common use include hydroxyprogesterone dehydroxylase, 16alpha-hydroxyprogesterone dehydroxylase, 16alpha-dehydroxylase, and 16alpha-hydroxyprogesterone hydro-lyase.
