... protein, Mfsd2b. Most intron/exon junctions are conserved between the two genes, suggesting that they are derived from a common ancestor. Mfsd2a and Mfsd2b share a 12 transmembrane α-helical domain structure that bears greatest similarity to that of the bacterial Na + /melibiose symporters. Confocal...

... per mg mitochondrial protein. (2) Three novel translocators exist to mediate l -lactate traffic across the inner mitochondrial membrane. An l -lactate/H + symporter was identified by measuring fluorimetrically the rate of endogenous pyridine nucleotide reduction. Consistently, l -lactate oxidation...

...) three novel separate translocators exist to mediate d -lactate traffic across the mitochondrial inner membrane: the d -lactate/H + symporter, which was investigated by measuring fluorimetrically the rate of endogenous flavin reduction, the d -lactate/oxoacid antiporter (which mediates both the d...
