MAH1 — Camelina sativa

Summary

CsMAH1 (CSA05G065900) on Camelina sativa chromosome 5 encodes a cytochrome P450 monooxygenase with midchain alkane hydroxylase activity, an oxidoreductase that incorporates molecular oxygen using NAD(P)H and binds heme and iron. The gene is associated with wax anabolism, long-chain fatty acyl-CoA metabolism, cholesterol metabolism, steroidogenesis, saponin anabolism, alkaloid metabolism, and lipid metabolism. Its product localises to the endoplasmic reticulum membrane and is also linked to the extracellular region and membrane. CsMAH1 has been connected to cuticular wax composition and drought tolerance. Studies of related cytochrome P450 genes in other species link the family to transpiration rate.
