Protein

ATPase RavA

Gene

ravA

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Functions as an ATPase. May play a role in metal insertion (metal-chelatase) or as a chaperone.

Enzyme regulationi

The complex formed with CadA represents a possible means of regulating RavA activity in response to acid stress conditions. This interaction results in an increase in RavA ATPase activity.

Kineticsi

RavA also has GTPase activity.
  1. KM=790 µM for ATP (at pH 7.5)

    pH dependencei

    Optimum pH is 7.5.
