Enolase signature


Enolase (EC is a glycolytic enzyme that catalyzes the dehydration of 2-phospho-D-glycerate to phosphoenolpyruvate [1]. It is a dimeric enzyme that requires magnesium both for catalysis and stabilizing the dimer. Enolase is probably found in all organisms that metabolize sugars. In vertebrates, there are three different tissue-specific isozymes: α present in most tissues, β in muscles and γ found only in nervous tissues.

Tau-crystallin, one of the major lens proteins in some fish, reptiles and birds, has been shown [2] to be evolutionary related to enolase.

As a signature pattern for enolase, we selected the best conserved region, it is located in the C-terminal third of the sequence.
