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.

Y+L amino acid transporter 2

Gene Name: Slc7a6

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. Also acts as an arginine/glutamine exchanger, following an antiport mechanism for amino acid transport, influencing arginine release in exchange for extracellular amino acids. Plays a role in nitric oxide synthesis via transport of L-arginine. Involved in the transport of L-arginine in monocytes. Reduces uptake of ornithine in retinal pigment epithelial cells (By similarity).

Y+L amino acid transporter 2

Gene Name: SLC7A6

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. Also acts as an arginine/glutamine exchanger, following an antiport mechanism for amino acid transport, influencing arginine release in exchange for extracellular amino acids. 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. Reduces uptake of ornithine in retinal pigment epithelial (RPE) cells

zeaxanthin epoxidase

Gene Name: ABA1

Zeaxanthin epoxidase is an enzyme in the chloroplast that catalyzes two reactions in the xanthophyll cycle: the conversion of zeaxanthin to antheraxanthin and the conversion of antheraxanthin to violaxanthin. It requires FAD as a cofactor.

Zeta-carotene desaturase, chloroplastic/chromoplastic

Gene Name: ZDS1

Plays a crucial role in plant growth and development. Is essential for the biosynthesis of carotenoids. Carotenoids are involved in different physiological processes, including coloration, photoprotection, biosynthesis of abscisic acid (ABA) and chloroplast biogenesis (PubMed:17468780, PubMed:24907342). Catalyzes the conversion of zeta-carotene to lycopene via the intermediary of neurosporene. It carries out two consecutive desaturations (introduction of double bonds) at positions C-7 and C-7'. Shows stereoselectivity toward trans C15-C15'zeta-carotene double bond. The zeta-carotene produced by the phytoene desaturase PDS has a C15-C15' double bond in the cis configuration and it requires isomerization before being recognized as substrate by ZDS. The main product is 7,9,7',9'-tetra-cis-lycopene (pro-lycopene) (PubMed:9914519).

Zona pellucida sperm-binding protein 2

Gene Name: ZP2

The mammalian zona pellucida, which mediates species-specific sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy, is composed of three to four glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP2 may act as a secondary sperm receptor.
