| DNA and amino acid sequence determination and analysis of the plastidic isozyme, genes accA-accD encode the 4 subunits, expression of the carboxyltransferase subunit | Pisum sativum |
| gene dedB, i.e. accD, encoding the beta subunit of the carboxyltransferase | Escherichia coli |
| genes acc1 and acc2, Oryza sativa lacks the accD gene which encodes for the biotin carboxyl carrier protein in plants other than the Gramineae | Oryza sativa |
| genes acc1 and acc2, Triticum aestivum lacks the accD gene which encodes for the biotin carboxyl carrier protein in plants other than the Gramineae | Triticum aestivum |
| subunit BCCP is encoded by 2 genes, while the other 3 subunits are single gene-encoded | Arabidopsis thaliana |
