 resolved a partial UGT2B7 structure of the C-terminal portion showing two dimeric domains with Rossman-like folds in complex.The Rossman fold typically binds nucleotide substrates, in this case the UDP-glucuronic acid cofactor involved in glucuronidation by UGT2B7.Generally, the C-terminus of UGT enzymes is highly conserved and binds the UDP-glucuronic acid cofactor, while the N-terminus (not resolved in this structure) is responsible for substrate binding.
