Dethiobiotin uptake and utilization by bacteria possessing bioYB operon.
Research in Microbiology 2023 August 27
Biotin is an essential vitamin for all organisms. Some bacteria cannot synthesize biotin and live by acquiring biotin from the environment. Bacterial biotin transporters (BioY) are classified into three mechanistic types. The first forms the BioMNY complex with ATPase (BioM) and transmembrane protein (BioN). The second relies on a promiscuous energy coupling module. The third functions independently. One-third of bioY genes spread in bacteria cluster with bioM and bioN on the genomes, and the rest does not. Interestingly, some bacteria have the bioY gene clustering with bioB gene, which encodes biotin synthase, an enzyme that converts dethiobiotin to biotin, on their genome. This bioY-bioB cluster is observed even though these bacteria cannot synthesize biotin. Azorhizobium caulinodans ORS571, a rhizobium of tropical legume Sesbania rostrata, is one of such bacteria. In this study using this bacterium, we demonstrated that the BioY linked to BioB could transport not only biotin but also dethiobiotin, and the combination of BioY and BioB contributed to the growth of A. caulinodans ORS571 in a biotin-deficient but dethiobiotin-sufficient environment. We propose that such environment universally exists in the natural world, and the identification of such environment will be a new subject in the field of microbial ecology.
