Organism

Synechocystis sp. (strain PCC 6803) [Complete proteome] [HAMAP]

Taxonomic identifier

1148 [NCBI]

Taxonomic lineage

Bacteria › Cyanobacteria › Chroococcales › Synechocystis

Protein attributes

Sequence length	77 AA.
Sequence status	Complete.
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.
