Here, we tested a number of model bacteria and compared the results to previous studies. We found that cobamide preferences and requirements vary broadly across bacteria, as well as in cobamide-dependent pathways within the same organism. 4/4

They are not only required by humans, but also by nearly all bacteria. However, only a subset of bacteria can synthesize them, making them important shared nutrients. 3/4

What are cobamides and why are they important? Cobamides, with nearly twenty different forms found naturally, are the vitamin B12 family of molecules. 2/4
