HER1 — Capsicum annuum

Summary

T459_08319 (HER1, VAMT) in pepper (Capsicum annuum) on chromosome 3 encodes a pyridoxal phosphate-dependent aminotransferase with 4-aminobutyrate:pyruvate transaminase activity (EC 2.6.1.119). The gene is associated with GABA catabolism, the GABA shunt, beta-alanine breakdown, succinate metabolism, and biotin, alkaloid, lignin, and phenylpropanoid anabolism. It has been linked to pungency, fruit quality, saline-alkali tolerance, drought tolerance, self-fertility, pollen tube guidance and elongation, root elongation, hypocotyl development, transpiration, light response, insect herbivory resistance, and E-2-hexenal response. The encoded protein localises to the plant-type vacuole, Golgi, mitochondria, and cytosol. Related genes in other species are linked to salt tolerance, fruit ripening, seed germination, and cell wall composition.
