Fig. 7From: CtpB is a plasma membrane copper (I) transporting P-type ATPase of Mycobacterium tuberculosisCopper accumulation in whole M. tuberculosis ΔctpB cells. The content of intracellular copper in M. tuberculosis wild-type and ΔctpB cells previously treated with 50 μM of CuSO4 was assessed by AAS-GF. The values of metal accumulation are shown as μg of Cu/g of dry pellet. The data are shown as the mean ± SEM from three independent experimentsBack to article page
