Protein

Urease subunit gamma

Gene

ureA

Organism
Streptococcus salivarius (strain 57.I)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Ureolysis may allow urea to be employed as a nitrogen source for growth and produces ammonia which may protect from killing at low pH.1 Publication

Catalytic activityi

Urea + H2O = CO2 + 2 NH3.UniRule annotation

Kineticsi

Urea concentrations in the oral cavity of humans normally range from 3 mM to 10 mM.
  1. KM=3.7 mM for urea (at pH 7.0 and 37 degrees Celsius)1 Publication

    pH dependencei

    Optimum pH is 7.0.1 Publication

    Temperature dependencei

    Optimum temperature is 60 degrees Celsius.1 Publication

    Pathwayi: urea degradation

    This protein is involved in step 1 of the subpathway that synthesizes CO(2) and NH(3) from urea (urease route).UniRule annotation
    Proteins known to be involved in this subpathway in this organism are:
    1. Urease subunit gamma (ureA), Urease subunit beta (ureB), Urease subunit alpha (ureC)
    This subpathway is part of the pathway urea degradation, which is itself part of Nitrogen metabolism.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes CO(2) and NH(3) from urea (urease route), the pathway urea degradation and in Nitrogen metabolism.
