To date, there is no report of any methyltransferase structure from the human intestine antibiotic resistant pathogen Bacteroides vulgatus. The protein BVU_3255 from B. vulgatus ATCC 8482 belongs to a SAM-dependent methyltransferase. Here, we report the crystal structure of apo BVU_3255, and its complexes with SAM and SAH, which revealed a typical class I Rossmann Fold Methyltransferase. Isothermal titration calorimetric studies showed that both SAM and SAH bind with equal affinity. The structural and sequence analysis suggested that BVU_3255 is a small molecule methyltransferase and involved in methylating the intermediates in ubiquinone biosynthesis pathway.
