- CTPase activity
Catalysis of the reaction: CTP + H2O = CDP + H+ + phosphate. May or may not be coupled to another reaction.
- glutathione transferase activity
Catalysis of the reaction: R-X + glutathione = H-X + R-S-glutathione. R may be an aliphatic, aromatic or heterocyclic group; X may be a sulfate, nitrile or halide group.
- sorbose reductase activity
Catalysis of the reaction: D-glucitol + NADP+ = L-sorbose + H+ + NADPH. The reaction may occur, to a minor extent, in the reverse direction.
- alpha-keto amide reductase activity
Catalysis of the reaction: alpha-keto amide + 2 H+ (from donor) = (R)-hydroxy amide. Alpha-keto amides are of the form R-CO-CONH2, where R may be aromatic or aliphatic.
- carotene epsilon hydroxylase activity
Catalysis of the reaction: alpha-carotene + O2 + reduced [NADPH--hemoprotein reductase] = alpha-cryptoxanthin + H(+) + H2O + oxidized [NADPH--hemoprotein reductase]. Zeinoxanthin may also be used as the substrate, in which case lutein is produced.
