A ribonucleoprotein complex that catalyzes cleavage of the leader sequence of precursor tRNAs (pre-tRNAs), generating the mature 5' end of tRNAs.

A ribonuclease P complex located in the mitochondrion of a eukaryotic cell, where it catalyzes the 5' endonucleolytic cleavage of precursor tRNAs to yield mature tRNAs. The subunit composition of mitochondrial ribonuclease P complexes varies between species. The complex contains a single RNA molecule and a single protein molecule in yeast (PMID:12045094), but comprises three proteins and lacks an RNA component in humans.

A ribonuclease P complex located in the cyanelle, where it catalyzes the 5' endonucleolytic cleavage of precursor tRNAs to yield mature tRNAs. The best characterized cyanelle ribonuclease P complex, from the alga Cyanophora paradoxa, contains a single RNA molecule that is necessary but not sufficient for catalysis, and several protein molecules.

A ribonuclease P complex that generally contains a single RNA molecule and several protein molecules. Examples of this complex are found in Archaeal species.

The lipid bilayer surrounding a vesicle associated with the Golgi apparatus.

Catalysis of the reaction: methane + NAD(P)H + H+ + O2 = methanol + NAD(P)+ + H2O.

The lipid bilayer surrounding a chitosome.

The lipid bilayer surrounding a coated vesicle.

Catalysis of the reaction: NADPH + H+ + 2 ferricytochrome c2 = NADP+ + 2 ferrocytochrome c2.

Catalysis of the transfer of electrons between pyridine nucleotides (obligatory two-electron carriers) and hemes or (2Fe-2S) centers (obligatory one-electron carriers) in respiration, photosynthesis, and many oxygenase systems.

The lipid bilayer surrounding a COPI-coated vesicle.

Catalysis of the reaction: reduced rubredoxin + NAD(P)+ = oxidized rubredoxin + NAD(P)H + H+.

Catalysis of the reaction: reduced rubredoxin + NADP+ = oxidized rubredoxin + NADPH + H+.

Catalysis of the reaction: NADPH + H+ + 2 ferrileghemoglobin = NADP+ + 2 ferroleghemoglobin.

Catalysis of the reaction: reduced rubredoxin + NAD+ = oxidized rubredoxin + NADH + H+.

OBSOLETE. An electron transfer flavoprotein that functions as a housekeeping protein that is synthesized only under certain specific growth conditions and receives electrons from the oxidation of specific substrates, e.g. trimethylamine, carnitine and in nitrogen fixation.

Catalysis of the reaction: NADP+ + trypanothione = NADPH + H+ + trypanothione disulfide.

OBSOLETE. An electron transfer flavoprotein that functions as a housekeeping protein that links acyl-CoA dehydrogenase reactions with the respiratory chain, such as in the fatty acid degradation pathway.

The lipid bilayer surrounding a dense granule of the type found in apicomplexan parasites.
