Protein Family Models

Acetyl co-enzyme A carboxylase carboxyltransferase is composed of an alpha and beta subunit. This protein family includes the alpha subunit and similar sequences. [1]. 10470374.

All of the members in this family are biotin dependent carboxylases. The carboxyl transferase domain carries out the following reaction; transcarboxylation from biotin to an acceptor molecule. There are two recognised types of carboxyl transferase. One of them uses acyl-CoA and the other uses 2-oxoacid as the acceptor molecule of carbon dioxide. All of the members in this family utilise acyl-CoA as the acceptor molecule. [1]. 8366018.

The enzyme acetyl-CoA carboxylase contains a biotin carboxyl carrier protein or domain, a biotin carboxylase, and a carboxyl transferase. This model represents the alpha chain of the carboxyl transferase for cases in which the architecture of the protein is as in E. coli, in which the carboxyltransferase portion consists of two non-identical subnits, alpha and beta.
