Abstract

We measured the proton leak across the inner membrane of liver mitochondria isolated from six different vertebrate species and from obese and control Zucker rats. Proton leak at 37 degrees C was similar in ratand pigeon, and in obese and control Zucker rats. Compared to rat, itwas lower in cane toad, shingleback lizard, and the Madeiran lizard Lacerta dugessi. Proton leak at 20 degrees C was similar in xenopus toad and higher in rainbow trout, compared to rat. In general, proton permeability and substrate oxidation activity were greater in liver mitochondria from endotherms than those from ectotherms. Analysis of this and previous data showed that proton leak per milligram of mitochondrial protein correlated with standard metabolic rate, and proton leak permilligram of inner membrane phospholipid correlated with 11 phospholipid fatty acid compositional parameters, including unsaturation index.
