haloperoxidase activity

Catalysis of the reaction: R-CH + a halogen + H2O2 = R-C-halogen + H2O.

halogenase activity

Catalysis of the reaction: R-CH + a halogen + oxygen donor = R-C-halogen +H2O.

flavin-dependent halogenase activity

Catalysis of the reaction: R-CH + a halogen + FADH2 + O2 = R-C-halogen + FAD + H2O.

D-lactate dehydrogenase (cytochrome) activity

Catalysis of the reaction: (R)-lactate + 2 [Fe(III)cytochrome c] = 2 [Fe(II)cytochrome c] + 2 H+ + pyruvate.

negative regulation of phospholipase C-activating phototransduction signaling pathway

Any process that stops, prevents or reduces the frequency, rate or extent of phospholipase C-activating phototransduction signaling pathway. Activated rhodopsin (R*) is inactivated by a two-step process: first, R* is phosphorylated by rhodopsin kinase which lowers the activity of R*. Second, the protein arrestin binds to phosphorylated R* to de-activate it.

25-hydroxycholecalciferol-24-hydroxylase activity

Catalysis of the hydroxylation of C-24 of 25-hydroxycholecalciferol (25-hydroxyvitamin D3) to form 24(R),25-dihydroxycholecalciferol.

peroxisome matrix targeting signal-1 binding

Binding to a type 1 peroxisome targeting signal, a tripeptide with the consensus sequence (S/A/C)-(K/R/H)-L.

(R,R)-butanediol dehydrogenase activity

Catalysis of the reversible reaction: (R,R)-butane-2,3-diol + NAD+ = (R)-acetoin + NADH + H+.

hydroxybutyrate-dimer hydrolase activity

Catalysis of the reaction: (R)-3-[(R)-3-hydroxybutanoyloxy]butanoate + H2O = 2 (R)-3-hydroxybutanoate + H+.

thiol oxidase activity

Catalysis of the reaction: 2 R'C(R)SH + O2 = R'C(R)S-S(R)CR' + 2 H2O2.
