Catalysis of the reaction: sn-glycerol 3-phosphate + NADP(+) = D-glyceraldehyde 3-phosphate + H(+) + NADPH.

OBSOLETE. The process in which a signal is conveyed via the xylem.

Catalysis of the reaction: cholate + NADP(+) = 3alpha,7alpha-dihydroxy-12-oxo-5beta-cholanate + H(+) + NADPH.

OBSOLETE. The process in which a signal is conveyed via the phloem.

Catalysis of the reaction: NAD+ + 7-alpha-hydroxycholesterol = NADH + H+ + 7-alpha-hydroxycholest-4-en-3-one.

OBSOLETE. The process in which a signal is conveyed via the lymphatic system.

Catalysis of the reaction: NAD+ + 2-methyl-3-hydroxybutyryl-CoA = NADH + H+ + 2-methylaceto-acetyl-CoA.

OBSOLETE. The process in which a signal is conveyed via the vascular system.

Catalysis of the reaction: indole-3-ethanol + NAD(+) = (indol-3-yl)acetaldehyde + H(+) + NADH.

Catalysis of the reaction: NADP+ + (5Z,13E)-(15S)-9-alpha,11-alpha,15-trihydroxyprosta-5,13-dienoate = NADPH + H+ + (5Z,13E)-(15S)-9-alpha,15-dihydroxy-11-oxoprosta-5,13-dienoate.

Catalysis of the reaction: indole-3-ethanol + NADP(+) = (indol-3-yl)acetaldehyde + H(+) + NADPH.

OBSOLETE. The process in which a signal is released and/or conveyed from one location to another.

Catalysis of the reaction: (1S,3R,4S)-3,4-dihydroxycyclohexane-1-carboxylate + NAD(+) = (1S,4S)-4-hydroxy-3-oxocyclohexane-1-carboxylate + H(+) + NADH.

OBSOLETE. The process in which a signal is conveyed via blood.

Catalysis of the reaction: NAD(P)+ + 3-beta-hydroxy-4-alpha-methyl-5-alpha-cholest-7-ene-4-beta-carboxylate = NAD(P)H + H+ + CO2 + 4-alpha-methyl-5-alpha-cholest-7-en-3-one.

Catalysis of the reaction: (R)-pantolactone + NADP+ = 2-dehydropantolactone + NADPH + H+. The reaction is A-specific (i.e. the pro-R hydrogen is transferred from the 4-position of reduced nicotinamide cofactor) with respect to NADP+.

OBSOLETE. The process in which a signal is conveyed via transcytosis. Transcytosis is the directed movement of endocytosed material through the cell and its exocytosis from the plasma membrane at the opposite side.
