Structure of human purine nucleoside phosphorylase in complex with L-Immucillin-H
Overview
Human purine nucleoside phosphorylase (PNP) was crystallized with, transition-state analogue inhibitors Immucillin-H and DADMe-Immucillin-H, synthesized with ribosyl mimics of l-stereochemistry. The inhibitors, demonstrate that major driving forces for tight binding of these analogues, are the leaving group interaction and the cationic mimicry of the, transition state, even though large geometric changes occur with, d-Immucillins and l-Immucillins bound to human PNP.
About this Structure
2Q7O is a Single protein structure of sequence from Homo sapiens with and as ligands. Active as Purine-nucleoside phosphorylase, with EC number 2.4.2.1 Known structural/functional Sites: and . Full crystallographic information is available from OCA.
