Chains	Accession	Name	Description	Comments	Source
A, B, C, D	PF00108	Thiolase, N-terminal domain (Thiolase_N)	Thiolase, N-terminal domain	Thiolase is reported to be structurally related to beta-ketoacyl synthase (Pfam:PF00109), and also chalcone synthase.	Domain
A, B, C, D	PF22691	Thiolase C-terminal domain-like (Thiolase_C_1)	Thiolase C-terminal domain-like	This domain is found C-terminal in a number of thiolases and their homologues. Thiolases are essential CoA-dependent enzymes in lipid metabolism. This domain folds into a four-stranded antiparallel beta-sheet with helices packed on one side.	Domain
E, F, G, H	PF12172	Rubredoxin-like zinc ribbon domain (DUF35_N) (DUF35_N)	Rubredoxin-like zinc ribbon domain (DUF35_N)	This domain has no known function and is found in conserved hypothetical archaeal and bacterial proteins. The domain is duplicated in Swiss:O53566. The structure of a DUF35 representative reveals two long N-terminal helices followed by a rubredoxin ...	This domain has no known function and is found in conserved hypothetical archaeal and bacterial proteins. The domain is duplicated in Swiss:O53566. The structure of a DUF35 representative reveals two long N-terminal helices followed by a rubredoxin-like zinc ribbon domain represented in this family and a C-terminal OB fold domain. Zinc is chelated by the four conserved cysteines in the alignment.	Domain
E, F, G, H	PF01796	DUF35 OB-fold domain, acyl-CoA-associated (OB_aCoA_assoc)	DUF35 OB-fold domain, acyl-CoA-associated	The structure of a DUF35 representative reveals two long N-terminal helices followed by a rubredoxin-like zinc ribbon domain and a C-terminal OB fold domain represented in this entry. OB-folds are frequently found to bind nucleic acids suggesting thi ...	The structure of a DUF35 representative reveals two long N-terminal helices followed by a rubredoxin-like zinc ribbon domain and a C-terminal OB fold domain represented in this entry. OB-folds are frequently found to bind nucleic acids suggesting this domain might bind to DNA or RNA (Topsan http://www.topsan.org/). Genomic context shows it to be adjacent to acyl-CoA transferase (http:/www.microbesonline.org/).	Domain
I, J, K, L	PF08541	3-Oxoacyl-[acyl-carrier-protein (ACP)] synthase III C terminal (ACP_syn_III_C)	3-Oxoacyl-[acyl-carrier-protein (ACP)] synthase III C terminal	This domain is found on 3-Oxoacyl-[acyl-carrier-protein (ACP)] synthase III EC:2.3.1.41, the enzyme responsible for initiating the chain of reactions of the fatty acid synthase in plants and bacteria.	Domain
