BtuB TonB-dependent transporters and BtuG surface lipoproteins form stable complexes for vitamin B <sub>12</sub> uptake in gut <i>Bacteroides</i>

2022-11-17

Abstract excerpt

<h4>ABSTRACT</h4> Vitamin B 12 (cobalamin) is the most complex vitamin and essential for many human gut microbes. However, cobalamin is synthesised only by a limited number of bacteria, making many gut microbes dependent on scavenging to meet their cobalamin requirements. Since bacterial densities in the gut are extremely high, competition for cobalamin is severe, making it a keystone micronutrient that shapes h...
