Structural study of rat thyroid transcription factor 1 homeodomain (TTF-1 HD) by nuclear magnetic resonance.

abstract：:Cytochrome oxidase o has been isolated from the obligately aerobic, methylotrophic bacterium Methylophilus methylotrophus in the form of a cytochrome cL-o complex. The latter is comprised of cytochrome cL (Mr 21 000) and cytochrome o (Mr 29 000) in a 1-2:1 ratio, possibly in association with one or more minor polypept...
