X-RAY ANALYSES OF PEPTIDE INHIBITOR COMPLEXES DEFINE THE STRUCTURAL BASIS OF SPECIFICITY FOR HUMAN AND MOUSE RENINS
Structural highlights
Disease[RENI_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] Function[RENI_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.

Publication Abstract from PubMedX-ray analyses have defined the three-dimensional structures of crystals of mouse and human renins complexed with peptide inhibitors at resolutions of 1.9 and 2.8 A, respectively. The exquisite specificity of renin arises partly from ordered loop regions at the periphery of the binding cleft. Although the pattern of main-chain hydrogen bonding in other aspartic proteinase inhibitor complexes is conserved in renins, differences in the positions of secondary structure elements (particularly helices) also lead to improved specificity in renins for angiotensinogen substrates. X-ray analyses of peptide-inhibitor complexes define the structural basis of specificity for human and mouse renins.,Dhanaraj V, Dealwis CG, Frazao C, Badasso M, Sibanda BL, Tickle IJ, Cooper JB, Driessen HP, Newman M, Aguilar C, et al.
