Catalysis of the transfer of a palmitoyl group to a carbon atom on the acceptor molecule.

Catalysis of the reaction: L-serine + pyruvate = 3-hydroxypyruvate + L-alanine.

Catalysis of the reaction: shikimate + NADP+ = 3-dehydroshikimate + NADPH + H+.

Catalysis of the reaction: ATP + shikimate = 3-phosphoshikimate + ADP + 2 H(+).

Catalysis of the reaction: S-adenosylmethioninamine + putrescine = 5'-methylthioadenosine + spermidine.

Catalysis of the reaction: H(2)O + sphingomyelin = ceramide + choline phosphate + H(+).

Catalysis of the hydrolysis of a glycerophospholipid.

Catalysis of the reaction: stearoyl-CoA + 2 ferrocytochrome b5 + O2 + 2 H+ = oleoyl-CoA + 2 ferricytochrome b5 + 2 H2O.

Catalysis of the reaction: acyl-CoA + reduced acceptor + O2 = desaturated-acyl-CoA + acceptor + 2 H2O.

Catalysis of the reaction: a 3-oxo-delta(5)-steroid = a 3-oxo-delta(4)-steroid.

Catalysis of the reaction: a steryl ester + H2O = a sterol + a fatty acid.

Catalysis of the reaction: 3-beta-hydroxyandrost-5-en-17-one 3-sulfate + H2O = 3-beta-hydroxyandrost-5-en-17-one + sulfate.

Catalysis of the reaction: succinate + CoA + nucleotide triphosphate = nucleotide diphosphate + phosphate + succinyl-CoA.

Catalysis of the reaction: ATP + succinate + CoA = ADP + succinyl-CoA + phosphate.

Catalysis of the reaction: GTP + succinate + CoA = GDP + succinyl-CoA + phosphate.
