---|---|---|
GNAT1_ARATH | function | Protein acetyltransferase with dual specificity triggering both N-alpha-acetylation (NTA) and epsilon-lysine acetylation (KA), possibly with a low efficiency or toward specific plastid substrates (PubMed:32633465). Involved in melatonin biosynthesis by catalyzing the formation of N-acetylserotonin (NAS) from serotonin and of melatonin (N-acetyl-5-methoxytryptamine) from 5-methoxytryptamine (5-MT) (PubMed:31698875). |
GNAT1_ARATH | similarity | Belongs to the acetyltransferase family. GNAT subfamily. |
GNAT1_ARATH | tissue specificity | Expressed in green tissues (PubMed:32633465). Accumulates mainly in flowers and young leaves, and, to a lower extent, in stems and mature leaves, but barely in roots (PubMed:31698875). |
