Serine hydroxymethyltransferase (SHM) is one of the hallmarks of one-carbon metabolism In plants, isoforms of SHM participate in photorespiration and/or transfer the one-carbon unit from L-serine to tetrahydrofolate (THF), hence producing 5,10-CH2-THF that is needed, e.g., for biosynthesis of methionine, thymidylate, and purines. These links highlight the importance of SHM activity in DNA biogenesis, its epigenetic methylations, and in stress responses. Plant genomes encode several SHM isoforms that localize to cytosol, mitochondria, plastids, and nucleus. In this work, we present a thorough functional and structural characterization of all seven SHM isoforms from Arabidopsis thaliana (AtSHM1-7). In particular, we analyzed tissue-specific expression profiles of the AtSHM genes. We also compared catalytic properties of the active AtSHM1-4 in terms of catalytic efficiency in both directions and inhibition by the THF substrate. Despite numerous attempts to rescue the SHM activity of AtSHM5-7, we failed, which points towards different physiol. functions of these isoforms. Comparative anal. of exptl. and predicted three-dimensional structures of AtSHM1-7 proteins indicated differences in regions that surround the entrance to the active site cavity. This study involved multiple reactions and reactants, such as (4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate (cas: 54-47-7Synthetic Route of C8H10NO6P).
(4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate (cas: 54-47-7) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the 蟺-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the 蟽 bonds. Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties. Synthetic Route of C8H10NO6P
