Chapter 24, Problem 4P

Interpretation Introduction

Interpretation:

A maximal separation between the malonyl transferase and the β-ketoacyl-ACP synthase active sites should be estimated.

Concept Introduction:

Fatty acid synthase is a multi-enzyme protein which catalyzes the fatty acid biosynthesis.Major function is catalyzing the formation of palmitate from acetyl CoA and malonyl CoA. Mammalian fatty acid synthase contains two identical protein subunits. Three catalytic domains are in N-terminal section which are β-ketoacyl-ACP synthase, malonyl/acetyl transferase and dehydrase. Four catalytic domains are in C-terminal section, which are enoyl reductase, ketoacyl reductase, acyl carrier protein and thioesterase. N terminal section and C terminal section is separated by 600 residues.
