phosphopyruvate hydratase M-CSA #311 | Yeast enolase (2-phospho-D-glycerate hydrolase) is a metalloenzyme which catalyses the reversible dehydration of D-2-phos-phoglycerate (PGA) to phosphoenolpyruvate (PEP). The enzyme has an absolute requirement for the presence of a divalent cation, as is characteristic of the enolase family. Mitochondrial targeting of tRK1 in yeast is achieved by the successive actions of enolase 2 and the precursor of the mitochondrial lysyl-tRNA synthetase (preMSK). At the mitochondrial outer membrane, preMSK takes over enolase to start the import process properly; A fraction of the canonical tRNA L-form tRK1 pool is deviated from the cytosolic translation process by the enolase 2, which favours the tRNA conformational change leading to the formation of the F-form. | Defined by 10 residues: SER:A-39HIS:A-159GLU:A-168GLU:A-211ASP:A-246GLU:A-295ASP:A-320LYS:A-345HIS:A-373LYS:A-396 | EC: 4.2.1.11 (PDB Primary Data) |
