Catalysis of the reaction: S-adenosyl-L-methionine + methylarsonite = S-adenosyl-L-homocysteine + dimethylarsinate.

regulation of cyclic nucleotide metabolism

Any process that modulates the frequency, rate or extent of cyclic nucleotide metabolism.

Catalysis of the reaction: dodecyl sulfate + H2O = SO4(2-) (sulfate) + H+ + 1-dodecanol.

A chromosome found in the mitochondrion of a eukaryotic cell.

The division of a mitochondrion within a cell to form two or more separate mitochondrial compartments.

A generic term for parts of cells prepared by disruptive biochemical techniques.

Interacting selectively with a peroxisomal targeting sequence, any of several sequences of amino acids within a protein that can act as a signal for the localization of the protein into the peroxisome.

Catalysis of the reaction: S-formylglutathione + H2O = glutathione + formate.
