Abstract

Species differences are known to exist with reference to LDH profile. A four-band isoenzyme pattern is a feature in most snakes, which is a deviation from the primitive ancestor. The LDH morphic state of two water snakes, Cerberus rhynchops and Xenochrophis piscator belonging to the same family Colubridae was selected for the geneological understanding since one of the species is a known salt tolerant. The study was undertaken to observe the fractions of the key isoenzyme LDH subunit diversity in an evolutionary backdrop.

Highlights

  • Lactate dehydrogenase (LDH) (EC 1.1.1.27) is an enzyme present in one form or other in wide variety of organisms including plants and animals

  • The LDH morphic state of two water snakes, Cerberus rhynchops and Xenochrophis piscator belonging to the same family Colubridae was selected for the geneological understanding since one of the species is a known salt tolerant

  • Biochemical characterizations of LDH proteins have suggested that gene duplication early in vertebrate evolution gave rise to Ldh-A and Ldh-B and that an additional locus, Ldh-C arose in a number of lineages more recently
