Structure of Protease1 from Pyrococcus horikoshii at room temperature in ChipX microfluidic device
Structural highlights
FunctionDEGLY_PYRHO Deglycase that catalyzes the deglycation of the Maillard adducts formed between amino groups of proteins and reactive carbonyl groups of glyoxals. Thus, functions as a protein deglycase that repairs methylglyoxal- and glyoxal-glycated proteins, and releases repaired proteins and lactate or glycolate, respectively. Deglycates cysteine, arginine and lysine residues in proteins, and thus reactivates these proteins by reversing glycation by glyoxals. Acts on early glycation intermediates (hemithioacetals and aminocarbinols), preventing the formation of advanced glycation endproducts (AGE) that cause irreversible damage (By similarity). Also displays proteolytic activity (PubMed:11114201).[UniProtKB:Q51732][1] Publication Abstract from PubMedDetermining optimal conditions for the production of well diffracting crystals is a key step in every biocrystallography project. Here, a microfluidic device is described that enables the production of crystals by counter-diffusion and their direct on-chip analysis by serial crystallography at room temperature. Nine 'non-model' and diverse biomacromolecules, including seven soluble proteins, a membrane protein and an RNA duplex, were crystallized and treated on-chip with a variety of standard techniques including micro-seeding, crystal soaking with ligands and crystal detection by fluorescence. Furthermore, the crystal structures of four proteins and an RNA were determined based on serial data collected on four synchrotron beamlines, demonstrating the general applicability of this multipurpose chip concept. A simple and versatile microfluidic device for efficient biomacromolecule crystallization and structural analysis by serial crystallography.,de Wijn R, Hennig O, Roche J, Engilberge S, Rollet K, Fernandez-Millan P, Brillet K, Betat H, Morl M, Roussel A, Girard E, Mueller-Dieckmann C, Fox GC, Olieric V, Gavira JA, Lorber B, Sauter C IUCrJ. 2019 Apr 19;6(Pt 3):454-464. doi: 10.1107/S2052252519003622. eCollection, 2019 May 1.
