CC   -!- FUNCTION: Carrier of the growing fatty acid chain in fatty acid
CC       biosynthesis. {ECO:0000255|HAMAP-Rule:MF_01217}.
CC   -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis. {ECO:0000255|HAMAP-
CC       Rule:MF_01217}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- PTM: 4'-phosphopantetheine is transferred from CoA to a specific serine
CC       of apo-ACP by AcpS. This modification is essential for activity because
CC       fatty acids are bound in thioester linkage to the sulfhydryl of the
CC       prosthetic group. {ECO:0000255|HAMAP-Rule:MF_01217}.
CC   -!- SIMILARITY: Belongs to the acyl carrier protein (ACP) family.
CC       {ECO:0000255|HAMAP-Rule:MF_01217}.
