What is Fatty-acyl-CoA synthase?

Fatty-acyl-CoA Synthase, or more commonly known as yeast fatty acid synthase , is an enzyme complex responsible for fatty acid biosynthesis, and is of Type I Fatty Acid Synthesis. Yeast fatty acid synthase plays a pivotal role in fatty acid synthesis. It is a 2.6 MDa barrel shaped complex and is composed of two, unique multi-functional subunits: alpha and beta. Together, the alpha and beta units are arranged in an α6β6 structure. The catalytic activities of this enzyme complex involves a coordination system of enzymatic reactions between the alpha and beta subunits. The enzyme complex therefore consists of six functional centers for fatty acid synthesis.
