I saw these on a same step of conversion of Malonyl CoA to Malonyl-ACP. Could anyone clarify this? I add that reference link below.
KEGG PATHWAY: Fatty acid biosynthesis - Chlorella variabilis (genome.jp)
In FAS i.e., fatty acid synthesis the chemical reaction is, Malonyl CoA+ Acyl-carrier protein↔ CoA+Malonyl-[acyl carrier protein]. In fact, there are two substrates for the enzyme concerned. Concerned enzyme is a transferase. The enzyme very often called as S-malonyltransferase may be termed as FabD, i.e., Acyl-carrier-protein- S- malonyltransferase.
Here is the BRENDA entry for this enzyme, with a list of synonyms.

The gene name is fabD. It is a common practice, at least in my experience, to use the gene name (capitalized) to refer to the protein, as a shortcut, since the formal names can be quite long.
According to PubChem result, both are same.
This one enzyme has 3 different names,
- [acyl-carrier-protein] S-malonyltransferase
- [acyl carrier protein]malonyltransferase
- FabD
