THT4 — Capsicum annuum

Summary

CaTHT4 (T459_21685) on pepper chromosome 8 encodes a tyramine N-feruloyltransferase with N-acetyltransferase activity, belonging to the GNAT domain-containing acyl-CoA acyltransferase family. The enzyme is localized to the cytoplasm. This gene is associated with responses to UV-A, UV-C, and general UV radiation, as well as fermentation and amino acid anabolism. It has also been connected to pungency. Studies of related genes in other species link the family to tyramine hydroxycinnamoyl transferase activity (EC 2.3.1.110) and, more distantly, to leaf curling.
