Biological function summary
NNMT impacts cell energy balance and gene expression regulation by influencing the levels of nicotinamide and methionine metabolites. This enzyme does not typically form part of a complex acting more so as an individual regulator of methylation reactions affecting cellular metabolism. Researchers find interest in NNMT for its role in modulating cellular growth and proliferation forming a link to both normal cellular functions and pathological conditions like cancer.
Pathways
NNMT has a significance in NAD+ metabolism and methionine salvage pathways. These pathways are essential in maintaining redox homeostasis and proper methylation status in cells. NNMT through its enzymatic activity interacts with SAM (S-adenosyl methionine) closely relating its function to methylation processes that involve other proteins such as SIRTs (Sirtuins) and NAMPT (Nicotinamide phosphoribosyltransferase) within these metabolic pathways.
常规信息
功能
Catalyzes the N-methylation of nicotinamide using the universal methyl donor S-adenosyl-L-methionine to form N1-methylnicotinamide and S-adenosyl-L-homocysteine, a predominant nicotinamide/vitamin B3 clearance pathway (PubMed : 21823666, PubMed : 23455543, PubMed : 8182091). Plays a central role in regulating cellular methylation potential, by consuming S-adenosyl-L-methionine and limiting its availability for other methyltransferases. Actively mediates genome-wide epigenetic and transcriptional changes through hypomethylation of repressive chromatin marks, such as H3K27me3 (PubMed : 23455543, PubMed : 26571212, PubMed : 31043742). In a developmental context, contributes to low levels of the repressive histone marks that characterize pluripotent embryonic stem cell pre-implantation state (PubMed : 26571212). Acts as a metabolic regulator primarily on white adipose tissue energy expenditure as well as hepatic gluconeogenesis and cholesterol biosynthesis. In white adipocytes, regulates polyamine flux by consuming S-adenosyl-L-methionine which provides for propylamine group in polyamine biosynthesis, whereas by consuming nicotinamide controls NAD(+) levels through the salvage pathway (By similarity). Via its product N1-methylnicotinamide regulates protein acetylation in hepatocytes, by repressing the ubiquitination and increasing the stability of SIRT1 deacetylase (By similarity). Can also N-methylate other pyridines structurally related to nicotinamide and play a role in xenobiotic detoxification (PubMed : 30044909).
