Xanthine dehydrogenase/oxidase

Gene Name: XDH

Key enzyme in purine degradation. Catalyzes the oxidation of hypoxanthine to xanthine. Catalyzes the oxidation of xanthine to uric acid. Contributes to the generation of reactive oxygen species.

P0A9M5

View in UniProt

Xanthine phosphoribosyltransferase

Gene Name: gpt

Involved in nucleoside metabolic process. Acts on guanine, xanthine and to a lesser extent hypoxanthine.

P45562

View in UniProt

Xanthosine permease

Gene Name: xapB

Involved in nucleoside transmembrane transporter activity. Nucleoside transport.

P45563

View in UniProt

Xanthosine phosphorylase

Gene Name: xapA

Involved in purine-nucleoside phosphorylase activity. The nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the nucleoside molecule, with the formation of the corresponding free bases and pentose-1-phosphate. This protein can degrade all purine nucleosides except adenosine and deoxyadenosine.

Q9C826

View in UniProt

xanthoxin dehydrogenase

Gene Name: ABA2

Xanthoxin dehydrogenase, located in the cytosol, catalyzes the fourth reaction in abscisic acid biosynthesis whereby xanthoxin is converted to abscisic aldehyde. It requires a molybdenum cofactor (MoCo).

xanthoxin transporter

Gene Name: ?

Xanthoxin transporter is theorized to export xanthoxin from the chloroplast into the cytosol for abscisic acid biosynthesis. It has yet to be discovered.

Xylose import ATP-binding protein XylG

Gene Name: xylG

Involved in nucleotide binding. Part of the ABC transporter complex XylFGH involved in xylose import. Responsible for energy coupling to the transport system (Probable). The XylFGH system can also transport ribose in absence of xylose.

Xylose isomerase

Gene Name: xylA

P00944

View in UniProt

Xylose isomerase

Gene Name: xylA

Involved in xylose isomerase activity. D-xylose = D-xylulose.

Q9FKK7

View in UniProt

xylose isomerase

Gene Name: XYLA

Xylose isomerase is an enzyme located in the cytosol that catalyzes the interconversion of aldose and ketose sugars. It requires two divalent metal ions as cofactors (e.g. manganese, magnesium).

P0ACI3

Xylose operon regulatory protein

Gene Name: xylR

Regulatory protein for the xylBAFGHR operon.

P0AGI4

View in UniProt

Xylose transport system permease protein xylH

Gene Name: xylH

Involved in transporter activity. Part of the binding-protein-dependent transport system for D-xylose. Probably responsible for the translocation of the substrate across the membrane.

Q9LF61

View in UniProt

xylulose 5-phosphate/phosphate translocator

Gene Name: XPT

Xylulose 5-phosphate/phosphate translocator preferentially transports xylulose 5-phosphate (but will also transport ribulose 5-phosphate) from the cytosol and into the chloroplast in exchange for phosphate. Xylulose 5-phosphate supplies the plastidic pentose phosphate pathway with intermediates, especially when under high demand.

Xylulose kinase

Gene Name: XKS1

P09099

View in UniProt

Xylulose kinase

Gene Name: xylB

Involved in phosphotransferase activity, alcohol group as acceptor. ATP + D-xylulose = ADP + D-xylulose 5- phosphate.

Y+L amino acid transporter 1

Gene Name: SLC7A7

Involved in the sodium-independent uptake of dibasic amino acids and sodium-dependent uptake of some neutral amino acids. Requires co-expression with SLC3A2/4F2hc to mediate the uptake of arginine, leucine and glutamine. Plays a role in nitric oxide synthesis in human umbilical vein endothelial cells (HUVECs) via transport of L-arginine. Involved in the transport of L- arginine in monocytes

Y+L amino acid transporter 1

Gene Name: Slc7a7

Involved in the sodium-independent uptake of dibasic amino acids and sodium-dependent uptake of some neutral amino acids. Requires coexpression with SLC3A2/4F2hc to mediate the uptake of arginine, leucine and glutamine. Plays a role in nitric oxide synthesis via transport of L-arginine, and is involved in the transport of L-arginine in monocytes (By similarity).
