From: CtpB is a plasma membrane copper (I) transporting P-type ATPase of Mycobacterium tuberculosis
Optimal conditions for Cu+ ATPase activity mediated by CtpB. The Cu+ ATPase activity was measured using plasma membranes isolated from M. smegmatis mc2155 expressing CtpB and membranes isolated from M. smegmatis transformed with the expression vector pMV261. The enzymatic parameters evaluated were: a temperature, b pH, and c cysteine concentration. The data correspond to the mean ATPases activity ± SEM derived from measurements of technical triplicate
