| additional information | UTP recognition mechanism, overview. UTP specificity is determined primarily by the two closely positioned carboxylic residues, D297/D421 and E300/E424, which coordinate a crucial water molecule indicated in TUT4/RET2, uracil base interactions with invariant amino acids N147, S148, Y189, D297, E300 of TUT4.
