Protein

Creatinine amidohydrolase

Gene
crnA
Organism
Pseudomonas putida (Arthrobacter siderocapsulatus)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Cyclic amidohydrolase that catalyzes the reversible conversion of creatinine to creatine. Is also active toward glycocyamidine, though the reaction rate is very low, but it is completely inert toward hydantoin and its derivatives.1 Publication

Catalytic activityi

Creatinine + H2O = creatine.2 Publications

Cofactori

Binds 2 Zn2+ ions per subunit. The Zn2+ in the metal 1 binding site can be replaced with Mn2+; however, the second zinc in metal binding site 2 is much more tightly bound and can not be replaced. The enzyme with one zinc and one manganese ion is more active than that with two zinc ions.2 Publications

Enzyme regulationi

Is markedly inactivated in vitro by heavy metal ions, N-bromosuccinimide, ethoxyformic anhydride, and dye-sensitized photooxidation.1 Publication

Kineticsi

  1. KM=26 mM for creatinine2 Publications
  2. KM=130 mM for creatine
  3. KM=200 mM for glycocyamidine

Vmax=390 µmol/min/mg enzyme for the forward reaction (creatine formation)

Vmax=1510 µmol/min/mg enzyme for the reverse reaction (creatinine formation)

Vmax=3.7 µmol/min/mg enzyme with glycocyamidine as substrate

pH dependencei

Optimum pH is 7-9 for the forward and reverse reactions.

Temperature dependencei

Retains 75% of the activity after incubation at 75 degrees Celsius for 30 minutes.

Miscellaneousi

Miscellaneous

The proposed catalytic mechanism involves two water molecules. The first molecule is a hydroxide ion that is bound as a bridge between the two metal ions and attacks the carbonyl carbon of the substrate. The second water molecule, that is bound to the carboxyl group of Glu-122 and to the metal 1, functions as a proton donor in catalysis.
