Here, we present the X-ray crystal structure of human N-acetyl serotonin methyltransferase (ASMT), the last enzyme of the melatonin biosynthesis pathway. Melatonin synthesis requires serotonin, which is first acetylated by the arylalkylamine N-acetyltransferase (AA-NAT) to produce N-acetyl serotonin (NAS) (Fig. 1A). Then, acetyl serotonin methyltransferase (ASMT, also known as hydroxyindole O-methyltransferase or HIOMT) produces melatonin by transferring a methyl group from the cofactor S-adenosyl-L-methionine (SAM) to NAS |

Here we systematically quantified ligand-induced interactions between 148 GPCRs and all 11 unique G alpha subunit C-termini. For each receptor, we probed chimeric G alpha subunit activation via a transforming growth factor-alpha (TGF alpha) shedding response in HEK293 cells lacking endogenous Gq/11- and G12/13- signaling. | We defined positive coupling if any member of the subfamily scored LogRAi ≥ -1 and negative coupling if all of the members scored LogRAi < -1 (Figure 3A-B). ROC analysis gives AUC = 0.78 (Figure S4A) when considering high-confidence known coupling data and suggested a threshold of LogRAi ≥ -1.0 for defining true couplings. | The score associated to this interaction has a LogRAi ≥ -1.0. |
