IPR026506

Description

IPR026506 is a GDP-L-galactose/GDP-D-glucose phosphorylase.

<p>GDP-D-glucose phosphorylase 1 (GDPGP1) is a specific and highly efficient GDP-D-glucose phosphorylase regulating the levels of GDP-D-glucose in cells [[cite:PUB00060530]]. This family also includes the GDP-L-galactose phosphorylases VTC2 and VTC2L (VTC5) from Arabidopsis, which use preferentially GDP-L-galactose and GDP-D-glucose as substrates and are part of the Smirnoff-Wheeler pathway for ascorbate biosynthesis in plants. They act as a phosphorylase rather than as transferases [[cite:PUB00070303], [cite:PUB00070304], [cite:PUB00153078], [cite:PUB00153077]].</p> <p>This entry also includes uncharacterized proteins from bacteria.</p>
