Biochemical characterization of the essential GTP-binding protein Obg of Bacillus subtilis.

Journal of bacteriology - 1 Dec 1994

Welsh K M, Trach K A, Folger C, Hoch J A

Abstract excerpt

An essential guanine nucleotide-binding protein, Obg, of Bacillus subtilis has been characterized with respect to its enzymatic activity for GTP. The protein was seen to hydrolyze GTP with a Km of 5.4 microM and a kcat of 0.0061 min-1 at 37 degrees C. GDP was a competitive inhibitor of this hydrolysis, with an inhibition constant of 1.7 microM at 37 degrees C. The dissociation constant for GDP from the Obg...
