Cloning and site-directed mutagenesis of human ADP-ribosylarginine hydrolase.
Mono-ADP-ribosylation of arginine is a reversible modification of proteins with NAD:arginine ADP-ribosyltransferases and ADP-ribosylarginine hydrolases catalyzing the opposing reactions in the cycle. ADP-ribosylarginine hydrolases differ in their dithiothreitol (DTT) requirements. Rat and mouse hydrolases require DTT for maximal activity, but calf, guinea pig, and human hydrolases are DTT-indep...
متن کاملConstruction of a recombinant vector for site-directed mutagenesis in Salmonella typhimurium
BACKGROUND: Among all common techniques in sitedirectedmutagenesis, λ Red recombinase system has beenwidely used to knock out chromosomal genes in bacteria. In thismethod, there is always the risk of DNA Linear digestion byhost's restriction enzymes that leads to the low frequency ofrecombination. OBJECTIVES:To overcome this, we constructeda recombinant vector to disrupt phoP gene in Salmonella...
متن کاملSite-Directed Mutagenesis Study
Structural elements of the rat 1.t-opioid receptor important in ligand receptor binding and selectivity were examined using a site-directed mutagenesis approach. Five single amino acid mutations were made, three that altered conserved residues in the ~ 8, and K receptors (Asn 15°t Ala, His297 to Ala, and Tyr326 to Phe) and wo de igned to test for ~i/8 selectivity (lie198 to Val and Va1202 to li...
متن کاملPolymerase and hydrolase activities of Bacillus subtilis levansucrase can be separately modulated by site-directed mutagenesis.
The levansucrase (sucrose:2,6-beta-D-fructan 6-beta-D-fructosyltransferase, EC 2.4.1.10) structural gene from a Bacillus subtilis mutant strain displaying a low polymerase activity was sequenced. Only one missense mutation changing Arg331 to His was responsible for this modified catalytic property. From this allele we created new mutations by directed mutagenesis, which modified the charge and ...
متن کاملSite-Directed Mutagenesis, Expression and Biological Activity of E. coli 5-Enolpyruvylshikimate 3-Phosphate Synthase Gene
Site-directed mutagenesis (SDM) as a powerful technique was used to change two important and conserved amino acids in 5-enolpyruvylshikimate 3- phosphate synthase (EPSPS) gene of E. coli. The mutations changed glycine 96 to alanine and alanine 183 to threonine. These two amino acids are very important for intraction of the wide spectrum herbicide, glyphosate, to EPSP synthase enzymes. By design...
