Protein attributes

Sequence length	77 AA.
Sequence status	Fragment.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Carrier of the growing fatty acid chain in fatty acid biosynthesis. HAMAP MF_01217
Pathway	Lipid metabolism; fatty acid biosynthesis. HAMAP MF_01217
Subcellular location	Cytoplasm By similarity HAMAP MF_01217.
Post-translational modification	4'-phosphopantetheine is transferred from CoA to a specific serine of apo-ACP by AcpS. This modification is essential for activity because fatty acids are bound in thioester linkage to the sulfhydryl of the prosthetic group. HAMAP MF_01217
Sequence similarities	Contains 1 acyl carrier domain.
