Protein xylosyltransferase In enzymology, a protein xylosyltransferase () is an enzyme that catalyzes the chemical reaction in which a beta-D-xylosyl residue is transferred from UDP-D-xylose to the sidechain oxygen atom of a serine residue in a protein. This enzyme belongs ...

Xyloglucan 6-xylosyltransferase In enzymology, a xyloglucan 6-xylosyltransferase () is an enzyme that catalyzes the chemical reaction in which an alpha-D-xylosyl residue is transferred from UDP-D-xylose to a glucose residue in xyloglucan, being attached by an alpha-1,6-D-xylosy ...

XYLT1 Xylosyltransferase 1 is an enzyme that in humans is encoded by the ''XYLT1'' gene. Xylosyltransferase (XT; EC 2.4.2.26) catalyzes the transfer of UDP-xylose to serine residues within XT recognition sequences of target proteins. Addition of this ...

XYLT2 Xylosyltransferase 2 is an enzyme that in humans is encoded by the ''XYLT2'' gene. Function The protein encoded by this gene is an isoform of xylosyltransferase, which belongs to a family of glycosyltransferases. This enzyme transfers xylose fr ...
