ATUSP (ARABIDOPSIS THALIANA UDP-SUGAR PYROPHOSPHORYLASE); UTP-monosaccharide-1-phosphate uridylyltransferase/ UTP:arabinose-1-phosphate uridylyltransferase/ UTP:galactose-1-phosphate uridylyltransferase/ UTP:glucose-1-phosphate uridylyltransferase/ UTP:xy. Identical to UDP-sugar pyrophosphorylase (USP) [Arabidopsis Thaliana] (GB:Q9C5I1;GB:Q9LTG1); similar to UDP-N-acetylglucosamine pyrophosphorylase-related [Arabidopsis thaliana] (TAIR:AT1G31070.2); similar to UDP-sugar pyrophospharylase (UDP-galactose/glucose pyrophosphorylase) (UGGPase) (GB:Q0GZS3); similar to hypothetical protein [Trifolium pratense] (GB:BAE71295.1); similar to unnamed pr
