The directed movement of a cofactor into, out of, within or between cells. A cofactor is a substance that is required for the activity of an enzyme or other protein.

Catalysis of the reaction: (S)-3-hydroxyacyl-CoA + NAD+ = 3-oxoacyl-CoA + NADH + H+.

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

A transporter of solutes that utilizes a carrier-mediated process to catalyze uniport, symport or antiport between aqueous phases on either side of a lipid membrane.

Signaling at short range between cells of different ancestry and developmental potential that results in one cell or group of cells effecting a developmental change in the other. This is often done by secretion of proteins by one cell which affects the neighboring cells and causes them to adopt a certain fate.

Catalysis of the reaction: thiosulfate + cyanide = SO3(2-) (sulfite) + thiocyanate.

Catalysis of the transport of a single molecular species across a membrane; transport is independent of the movement of any other molecular species.

Enables the directed movement of vitamins into, out of, within or between cells. A vitamin is one of a number of unrelated organic substances that occur in many foods in small amounts and that are necessary in trace amounts for the normal metabolic functioning of the body.

Catalyze the transport of two or more molecular species across a membrane, transport being in the same direction.

Enables the directed movement of a cofactor into, out of, within or between cells. A cofactor is a substance that is required for the activity of an enzyme or other protein.

Catalysis of the reaction: L-threonine + H2O = 2-oxobutanoate + NH3 + H2O.

Catalysis of the reaction: solute(out) + cation(out) = solute(in) + cation(in).

Enables the directed movement of a coenzyme into, out of, within or between cells. A coenzyme is any of various nonprotein organic cofactors that are required, in addition to an enzyme and a substrate, for an enzymatic reaction to proceed.

Catalysis of the reaction: O-phospho-L-homoserine + H2O = L-threonine + phosphate.
