2.1.1.267 evolution the catalytic activity of Paeonia tenuifolia PtAOMT is much lower than that of Paeonia suffruticosa PsAOMT (approximately 60fold lower), the two enzymes show identical substrate specificity 757323 2.1.1.267 evolution the torenia A3'5'OMT shares 52-72% amino acid sequence identity with other AOMTs and belongs to the group A1 methyltransferase family that also includes caffeoyl CoA O-methyltransferase 757955 2.1.1.267 evolution the VvAOMT genes cluster results from gene duplication 721944 2.1.1.267 malfunction downregulation of AnthOMT in planta decreases the representation of methylated anthocyanins in tomato tissues as well as overall anthocyanin accumulation 736999 2.1.1.267 malfunction the AOMT2 gene presents two SNPs associated with methylation level. These mutations, probably leading to a structural change of the AOMT2 protein, significantly affect the enzyme specific catalytic efficiency for the 3'-O-methylation of delphinidin 3-O-beta-D-glucoside 721944 2.1.1.267 metabolism CrOMT2 is involved in the biosynthesis of flavonol glycosides and anthocyanins in Catharanthus roeus 637316 2.1.1.267 metabolism partial overview over the anthocyanin biosynthetic pathway of Torenia hybrida 757955 2.1.1.267 metabolism spatiotemporal transcriptome analysis indicates that genes involved in the early part of the flavonoid biosynthetic pathway are strongly expressed during early-petal development and that those in the late part at late-flower opening stages, but they are rarely expressed in leaves 757956 2.1.1.267 additional information anthocyanidin analysis in Nierembergia petals expressing the Torenia A3'5'OMT gene, overview 757955 2.1.1.267 additional information enzyme structure homology modeling using the three-domensional structure of caffeoyl-CoA 3-O-methyltransferase (CCoAOMT, PDB ID 1SUI) from alfalfa, substrate binding sites are predicted by docking Cy3G5G with the PsAOMT dimer 3D model. Molecular model of the PsAOMT active site. Structure-function analysis 757323 2.1.1.267 additional information enzyme structure homology modeling using the three-domensional structure of caffeoyl-CoA 3-O-methyltransferase (CCoAOMT, PDB ID 1SUI) from alfalfa. Structure-function analysis 757323 2.1.1.267 additional information ratio of methylated/non-methylated anthocyanins in berry skin of 32 unrelated cultivars, QTL mapping of anthocyanin methylation level, overview 721944 2.1.1.267 physiological function role of the enzyme in the diversification of tomato anthocyanins 736999 2.1.1.267 physiological function the enzyme is involved in biosynthesis of the blue flower color of Nemophila menziesii, which is derived from a metalloanthocyanin, nemophilin. Nemophilin comprises petunidin-3-O-[6-O-(trans-4-coumaroyl)-beta-glucoside]-5-O-[6-O-(malonyl)-beta-glucoside], apigenin-7-O-beta-glucoside-4'-O-(6-O-malonyl)-beta-glucoside, and Mg2+ and Fe3+ ions 757956 2.1.1.267 physiological function VvAOMT2 expression has no direct regulatory effect on anthocyanin methylation, transcriptional regulation of AOMTs and effects on anthocyanin methylation patterns, overview 721944
