Os. Klyachko et Nd. Ozernyuk, FUNCTIONAL AND STRUCTURAL-PROPERTIES OF LACTATE-DEHYDROGENASE FROM EMBRYOS OF DIFFERENT FISHES, Comparative biochemistry and physiology. B. Comparative biochemistry, 119(1), 1998, pp. 77-80
Functional and structural properties of L-lactate dehydrogenase (LDH,
EC 1.1.1.27) from embryos of various fish species (Atlantic salmon, ra
inbow trout, autumn cisco, least [Siberian] cisco, Siberian sturgeon,
sterlet, leach, carp, goldfish, and zebrafish) were analysed. The mini
mum K-m for pyruvate from embryos is correlated with the optimal tempe
ratures of development in nature. LDH from embryos of fish adapted to
low environmental temperatures (salmon and rainbow trout) shows lower
Arrhenius activation energy and thermal stability values, than those f
rom embryos of other fish species. (C) 1998 Elsevier Science Inc.
