GENERAL STABILITY
ORGANISM
UNIPROT
LITERATURE
50% loss of activity after 10 min in air
-
90% loss of activity after 8 days in the presence of oxygen, increasing ionic strength causes 10-40% reversible inhibition
-
high loss of activity when purified in air
-
photolability is dependent upon the oxidation state
-
pressure of 50.7 MPa destabilizes the enzyme
pressure of 50.7 MPa has a substantial stabilizing effect on the enzyme
the half-life for inactivation of the hydrogenase at pressure of 1.0 MPa is 28 min
-
the half-life for inactivation of the hydrogenase at pressure of 1.0 MPa is 30 min
-
the half-life for inactivation of the hydrogenase at pressure of 1.0 MPa is 49 min
-
the half-life for inactivation of the hydrogenase at pressure of 1.0 MPa is 96 min
