Function

EBO_DROME Nonribosomal peptide synthase which is required for the regulation of histamine and dopamine levels in various tissues through their condensation with beta-alanine (PubMed:12900414, PubMed:19715698, PubMed:25229196, PubMed:30705105). In epithelial glial cells, plays an essential role in the inactivation of histamine, the main neurotransmitter in the optical nerve system, by catalyzing the conversion of histamine into carcinine (PubMed:5782111, PubMed:12486147, PubMed:12900414, PubMed:25229196, PubMed:30705105). In the cuticle, catalyzes the condensation of beta-alanine with dopamine to form beta-alanyl-dopamine (NBAD), a metabolite involved in the pigmentation and sclerotization of the insect cuticle (PubMed:8580497, PubMed:11934851). Also, regulates the cuticular hydrocarbon composition in females (PubMed:31118901). Acts downstream of the body clock to regulate circadian behavioral rhythms (PubMed:17678856). Can also condense beta-alanine with biogenic amines tyramine, octopamine, and serotonin in vitro (PubMed:12900414, PubMed:19715698).^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8] ^[9] ^[10]

Publication Abstract from PubMed

The protein Ebony from Drosophila melanogaster plays a central role in the regulation of histamine and dopamine in various tissues through condensation of these amines with beta-alanine. Ebony is a rare example of a nonribosomal peptide synthetase (NRPS) from a higher eukaryote and contains a C-terminal sequence that does not correspond to any previously characterized NRPS domain. We have structurally characterized this C-terminal domain and have discovered that it adopts the aryl-alkylamine-N-acetyl transferase (AANAT) fold, which is unprecedented in NRPS biology. Through analysis of ligand-bound structures, activity assays, and binding measurements, we have determined how this atypical condensation domain is able to provide selectivity for both the carrier protein-bound amino acid and the amine substrates, a situation that remains unclear for standard condensation domains identified to date from NRPS assembly lines. These results demonstrate that the C terminus of Ebony encodes a eukaryotic example of an alternative type of NRPS condensation domain; they also illustrate how the catalytic components of such assembly lines are significantly more diverse than a minimal set of conserved functional domains.
