4.1.1.18 evolution certain enterobacteria exert evolutionary pressure on the lysine decarboxylase towards the macromolecular cage-like assembly with AAA+ ATPase RavA, implying that this complex may have an important function under particular stress conditions. The C-terminal beta-sheet of a lysine decarboxylase is a highly conserved signature allowing to distinguish between LdcI and LdcC. RavA is binding to LdcI, but is not capable of binding to LdcC, LDC sequence comparisons and phylogenetic analysis 749315 4.1.1.18 evolution Selenomonas ruminantium SrLDC shows much lower pyridoxal 5'-phosphate affinity than other pyridoxal 5'-phosphate-dependent enzymes. The highly flexible active site contributes to the low affinity for pyridoxal 5'-phosphate in SrLDC 749101 4.1.1.18 evolution the L-lysine decarboxylase (LDC) genes from Escherichia coli include genes cadA and ldcC encoding the acid-inducible enzyme CadA and the constitutive LDCc, respectively 749366 4.1.1.18 metabolism changes in the contents of plant biogenic amines (putrescine, cadaverine, spermidine, tryptamine, spermine and histamine) and key enzymes of their biosynthesis, i.e. lysine decarboxylase (LDC), tyrosine decarboxylase, and ornithine decarboxylase (ODC) in galls and other parts of Siberian elm (Ulmus pumila) leaves during the galling process caused by the aphid Tetraneura ulmi first instar larvae, overview 747444 4.1.1.18 additional information compared to the activity of lysine/ornithine decarboxylase from Selenomonas ruminantium and from Vibrio vulnificus, the cadaverine producing activity of enzyme gtLDC is severalfold reduced 748513 4.1.1.18 additional information construction of a pseudoatomic model of the LdcI-RavA cage based on its cryo-electron microscopy map and yo-electron microscopy 3D reconstructions of the Escherichia coli LdcI and LdcC at optimal pH, overview. RavA is not capable of binding to LdcC. Conformational rearrangements in the enzyme LdcI active site, overview 749315 4.1.1.18 additional information due to the flexible pyridoxal 5'-phosphate binding site, the protein undergoes an open/closed conformational change at the PLP binding site depending on the pyridoxal 5'-phosphate binding. Especially, two loops located in the vicinity of the pyridoxal 5'-phosphate binding site, the pyridoxal 5'-phosphate stabilization loop (PS-loop) and the regulatory loop (R-loop), undergo a significant structural movement depending on the pyridoxal 5'-phosphate binding 749101 4.1.1.18 additional information Escherichia coli AAA+ ATPase RavA is not capable of binding to LdcC 749315 4.1.1.18 additional information optimization of the EcLdcC-catalyzed whole-cell biotransformation, overview -, 746801 4.1.1.18 additional information structure of enzyme SrLDC in complex with pyridoxal 5'-phosphate and cadaverine and binding mode of cofactor and substrate, overview 749097
