Bioactive brassinosteroid levels are also modulated by a variety of inactivation or catabolic reactions, including epimerization, oxidation, hydroxylation, sulfonation, and conjugation to glucose or lipids.

Active brassinosteroids are also regulated by brassinosteroid-dependent negative feedback mechanisms attenuation which is brought about by the downregulation of brassinosteroid biosynthetic genes and the upregulation of genes involved in brassinosteroid catabolism.
