In enzymology a tRNA-queuosine beta-mannosyltransferase (EC 2.4.1.110) is an enzyme that catalyzes the chemical reactionGDP-mannose + tRNAAsp-queuosine GDP + tRNAAsp-O-5-beta-D-mannosylqueuosineThus the two substrates of this enzyme are GDP-mannose and tRNAAsp-queuosine whereas its two products are GDP and tRNAAsp-O-5”-beta-D-mannosylqueuosine.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
