Function and Biology Details

Reactions catalysed: 
Myristoyl-CoA + acetyl-CoA = 3-oxopalmitoyl-CoA + CoA
(1a) [acetyl-CoA C-acyltransferase]-S-acyl-L-cyteine + acetyl-CoA = 3-oxoacyl-CoA + [acetyl-CoA C-acyltransferase]-L-cyteine
(1a) acetyl-CoA + [acetyl-CoA C-acetyltransferase]-L-cysteine = [acetyl-CoA C-acetyltransferase]-S-acetyl-L-cysteine + CoA
