Growth and ATPase activity of <i>Mmm</i> T1/44 and the Δ619 mutant.

<p><b>A</b>. Growth of <i>Mmm</i> T1/44 (▪) and Δ619 (□) in Hayflick medium at 37°C. <b>B</b>. Rate of release of Pi from ATP in the presence of membrane preparations from T1/44 (▪) and Δ619 (□). The figure shows representative results of five independent experiments. <b>C</b>. Rate of release of Pi from ATP in the presence of membrane preparations from T1/44 (▪) and Δ619 (□) transformed with the control plasmid pMYSO1, and Δ619 complemented with the MSC_0619 (α-like) and MSC_0618 (β-like) proteins, generated from the plasmid pCC1 (▴).
