Eukaryotic UGPase catalyses the synthesis of UDP-Glucose; UGPase (UDP-Glucose Pyrophosphorylase) catalyzes the reversible production of UDP-Glucose and pyrophosphate (PPi) from Glucose-1-phosphate and UTP. UDP-glucose plays pivotal roles in galactose utilization, in glycogen synthesis, and in the synthesis of the carbohydrate moieties of glycolipids, glycoproteins, and proteoglycans. UGPase is found in both prokaryotes and eukaryotes. Interestingly, while the prokaryotic and eukaryotic forms of UGPase catalyze the same reaction, they share low sequence similarity. This family consists of mainly eukaryotic UTP-glucose-1-phosphate uridylyltransferases.

Eukaryotic UGPase-like includes UDPase and UDPGlcNAc pyrophosphorylase enzymes; This family includes UDP-Glucose Pyrophosphorylase (UDPase) and UDPGlcNAc pyrophosphorylase enzymes. The two enzymes share significant sequence and structure similarity. UDP-Glucose Pyrophosphorylase catalyzes a reversible production of UDP-Glucose and pyrophosphate (PPi) from Glucose-1-phosphate and UTP. UDP-glucose plays pivotal roles in galactose utilization, in glycogen synthesis, and in the synthesis of the carbohydrate moieties of glycolipids , glycoproteins , and proteoglycans . UDP-N-acetylglucosamine (UDPGlcNAc) pyrophosphorylase (UAP) (also named GlcNAc1P uridyltransferase), catalyzes the reversible conversion of UTP and GlcNAc1P from PPi and UDPGlcNAc, which is a key precursor of N- and O-linked glycosylations and is essential for the synthesis of chitin (a major component of the fungal cell wall) and of the glycosylphosphatidylinositol (GPI) linker anchoring a variety of cell surface proteins to the plasma membrane. In bacteria, UDPGlcNAc represents an essential precursor for both peptidoglycan and lipopolysaccharide biosynthesis.

UDPGlcNAc pyrophosphorylase catalayzes the synthesis of UDPGlcNAc; UDP-N-acetylglucosamine (UDPGlcNAc) pyrophosphorylase (UAP) (also named GlcNAc1P uridyltransferase), catalyzes the reversible conversion of UTP and GlcNAc1 to PPi and UDPGlcNAc. UDP-N-acetylglucosamine (UDPGlcNAc), the activated form of GlcNAc, is a key precursor of N- and O-linked glycosylations. It is essential for the synthesis of chitin (a major component of the fungal cell wall) and of the glycosylphosphatidylinositol (GPI) linker which anchors a variety of cell surface proteins to the plasma membrane. In bacteria, UDPGlcNAc represents an essential precursor for both peptidoglycan and lipopolysaccharide biosynthesis. Human UAP has two isoforms, resulting from alternative splicing of a single gene and differing by the presence or absence of 17 amino acids. UDPGlcNAc pyrophosphorylase shares significant sequence and structure conservation with UDPglucose pyrophosphorylase.

UGGPase catalyzes the synthesis of UDP-Glucose/UDP-Galactose; UGGPase: UDP-Galactose/Glucose Pyrophosphorylase catalyzes the reversible production of UDP-Glucose/UDP-Galactose and pyrophosphate (PPi) from Glucose-1-phosphate/Galactose-1-phosphate and UTP. Its dual substrate specificity distinguishes it from the single substrate enzyme UDP-glucose pyrophosphorylase. It may play a key role in the galactose metabolism in raffinose oligosaccharide (RFO) metabolizing plants. RFO raffinose is a major photoassimilate and is a galactosylderivative of sucrose (Suc) containing a galactose (Gal) moiety. Upon arriving at the sink tissue, the Gal moieties of the RFOs are initially removed by alpha-galactosidase and then are phosphorylated to Gal-1-P. Gal-1-P is converted to UDP-Gal. The UDP-Gal is further metabolized to UDP-Glc via an epimerase reaction. The UDP-Glc can be directly utilized in cell wall metabolism or in Suc synthesis. However, for the Suc synthesis UDP-Glc must be further metabolized to Glc-1-P. This can be carried out either by the UGPase in the reverse direction or by the dual substrate PPase itself operating in the reverse direction. According to the latter possibility, the three-step pathway of Gal-1-P to Glc-1-P could be carried out by a single PPase, functioning sequentially in reverse directions separated by the epimerase reaction.
