Distribution of genes encoding the microbial non-oxidative reversible hydroxyarylic acid decarboxylases/phenol carboxylases.
Bacterial non-oxidative, reversible multi subunit hydroxyarylic acid decarboxylases/phenol carboxylases are encoded by the three clustered genes, B, C, and D, of approximately 0.6, 1.4, and 0.2 kb, respectively. There are more than 160 homologues in the database with significant similarity to gene B (homology to ubiX) and C (ubiD) distributed in all three microbial domains, however, homologues to gene D, are not numerous ( approximately 15). The occurrence of the entire BCD gene cluster encoding for either identified or presumptive hydroxyarylic acid decarboxylase to date has been revealed in Sedimentibacter hydroxybenzoicus (unique genes arrangement CDB), Streptomyces sp. D7, Bacillus subtilis, B. licheniformis, E. coli O157:H7, Klebsiella pneumoniae, Enterobacter cloacae, Shigella dysenteriae, Salmonella enterica, S. paratyphi, S. typhimurium, S. bongori, and S. diarizonae. The corresponding genes from S. hydroxybenzoicus, B. subtilis, Streptomyces sp. D7, E. coli O157:H7, K. pneumoniae, and S. typhimurium were cloned and expressed in E. coli DH5alpha (void of analogous genes), and shown to code for proteins exhibiting non-oxidative hydroxyarylic acid decarboxylase activity.
