Can use fatty acyl thioesters of ACP (C2 to C16) as substrates, as well as fatty acyl thioesters of Co-A (C4 to C16). beta-ketoacyl-acyl carrier protein synthetase activity RHEA:65312 RHEA:41884 RHEA:41800 acyl-malonyl acyl carrier protein-condensing enzyme activity RHEA:42252 RHEA:47824 beta-ketoacyl-ACP synthase II activity 3-oxoacyl-[acyl-carrier protein] synthase activity beta-ketoacylsynthase activity fatty acid condensing enzyme activity RHEA:55040 RHEA:65308 RHEA:41836 RHEA:41916 MetaCyc:3-OXOACYL-ACP-SYNTH-RXN ketoacyl-ACP synthase activity beta-ketoacyl acyl carrier protein synthase activity RHEA:42248 RHEA:22836 beta-ketoacyl-ACP synthase I activity EC:2.3.1.41 RHEA:54940 MetaCyc:2.3.1.179-RXN RHEA:14565 RHEA:41868 RHEA:41900 acyl-malonyl(acyl-carrier-protein)-condensing enzyme activity GO:0033817 acyltransferase activity, transferring groups other than amino-acyl groups
