MetaCyc Enzyme: alcaligin synthetase

Gene: alcC Accession Numbers: G-11646 (MetaCyc), BB3895

Species: Bordetella bronchiseptica

Summary:
The alcC gene is located in the alacaligin biosynthetic cluster and is involved in alcaligin synthesis [Kang96a, Giardina97]. The gene is highly homologous to several genes involved in the biosynthesis of siderophores in other bacteria, including iucC, pubC and desD. A transposon mutant with insertion into the alcC gene was not able to produce alcaligin [Pradel98].

Although the product of this gene has not been characterized biochemically yet, it is is proposed to catalyze the ATP-mediated condensation and cyclization of two 3-[4-amino-3-hydroxybutyl]-hydroxy-carbamoyl-propanoate monomers into alcaligin, via the free intermediate pre-alcaligin. The mutation could be complemented by introduction of the wild type gene [Challis05].

Molecular Weight of Polypeptide: 69.973 kD (from nucleotide sequence), 59.0 kD (experimental) [Pradel98 ]
