the fact that membrane-bound , cold-stable , oligomycin-sensitive atpase activity is present in poky ( with an activity of 1.93 +/- 0.03 mumol/min-mg of protein compared with 1.33 +/- 0.07 mumol/min-mg of protein in the wild-type strain ) and also in chloramphenicol-grown wild-type cells suggests that products of mitochondrial protein synthesis play only a limited role in the attachment of the mitochondrial atpase to the membrane in neurospora . poky also contains a second form of mitochondrial atpase , which has an activity of 1.5 +/- 0.2 mumol/min-mg of protein , is oligomycin sensitive but cold labile , and presumably is attached less firmly to the mitochondrial membrane .
