CRYSTALLOGRAPHIC STUDIES ON THE BINDING MODES OF P2-P3 BUTANEDIAMIDE RENIN INHIBITORS
Structural highlights
DiseaseRENI_HUMAN Defects in REN are a cause of renal tubular dysgenesis (RTD) [MIM:267430. RTD is an autosomal recessive severe disorder of renal tubular development characterized by persistent fetal anuria and perinatal death, probably due to pulmonary hypoplasia from early-onset oligohydramnios (the Potter phenotype).[1] Defects in REN are the cause of familial juvenile hyperuricemic nephropathy type 2 (HNFJ2) [MIM:613092. It is a renal disease characterized by juvenile onset of hyperuricemia, slowly progressive renal failure and anemia.[2] FunctionRENI_HUMAN Renin is a highly specific endopeptidase, whose only known function is to generate angiotensin I from angiotensinogen in the plasma, initiating a cascade of reactions that produce an elevation of blood pressure and increased sodium retention by the kidney. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe binding modes of three peptidomimetic P2-P3 butanediamide renin inhibitors have been determined by x-ray crystallography. The inhibitors are bound with their backbones in an extended conformation, and their side chains occupying the S5 to S1' pockets. A (2-amino-4-thiazolyl)methyl side chain at the P2 position shows stronger hydrogen-bonding and van der Waals interactions with renin than the His side chain, which is present in the natural substrate. The ACHPA-gamma-lactam transition state analog has similar interactions with renin as the dihydroxyethylene transition state analog.
