Web二氢乳清酸脱氢酶(DHODH)是由人类16号染色体上的DHODH基因编码的酶。 由该基因编码的酶在嘧啶的从头合成(de novo synthesis)中催化第四步酶促步骤,即泛醌介导的二氢乳清酸氧化为乳清酸。 该蛋白是位于线粒体内膜(IMM)外表面的线粒体蛋白。 这种酶的抑制剂用于治疗自體免疫性疾病,如类风湿 ... Purines are biologically synthesized as nucleotides and in particular as ribotides, i.e. bases attached to ribose 5-phosphate. Both adenine and guanine are derived from the nucleotide inosine monophosphate (IMP), which is the first compound in the pathway to have a completely formed purine ring system. Inosine monophosphate is synthesized on a pre-existing ribose-phosphate thr…

WebGuanosine monophosphate reductase (EC 1.7.1.7) catalyzes the irreversible NADPH-dependent reductive deamination of guanosine monophosphate (GMP) to inosine … GMP reductase EC 1.7.1.7 (Guanosine 5'-monophosphate oxidoreductase ) is an enzyme that catalyzes the irreversible and NADPH-dependent reductive deamination of GMP into IMP. NADPH + guanosine 5-phosphate = NADP + inosine 5-phosphate + NH3 By converting guanosine … See more A crystal structure of hGMPR2 was obtained, and the model shows that hGMPR2 is a homotetramer that consist of a mix of alpha helices and beta sheets (parallel and antiparallel). Each monomer interacts with each … See more The rat version of GMPR is expressed in brown adipose tissue (BAT) when certain conditions triggers its response and it is mainly present in the kidney, as well as cardiac and skeletal muscle. One of these conditions include cold stimulation. When the organism is … See more • Purine metabolism See more It has been realized that GMPR and its products increases in Alzheimer's disease. The GMPR gene encodes for the protein GMPR1 (GMP reductase enzyme) that catalyzes the reaction for converting GMP to IMP. IMP can also be converted to AMP and adenosine (A). … See more • GMP+reductase at the US National Library of Medicine Medical Subject Headings (MeSH) • Proposed catalytic mechanism: See more dyndns remote access setup
