Biochem/physiol Actions
9-Amino-6-chloro-2-methoxyacridine (ACMA) is a versatile fluorescent molecule that exhibits pH-sensitive fluorescence, with high intensity at physiological pH and quenching upon protonation, coupled with decreased membrane permeability. 9-ACMA functions as a DNA intercalator, preferentially binding to poly(dA-dT) sequences over poly(dG-dC), with excitation/emission maxima around 410/480 nm, compatible with various UV light sources. ACMA interacts with energized membranes and undergoes fluorescence quenching in response to transmembrane pH gradients. It is extensively employed to monitor cation and anion movement across membranes and to study the proton-pumping activity of various membrane-bound ATPases. ACMA has the capability to induce frameshift mutations as well as transversion and transition mutations. Additionally, it can cause base-pair substitutions in the presence of S9 mix.

Chloroplast ATP synthase (CFoCF1) synthesizes ATP by using a proton electrochemical gradient across the thylakoid membrane, termed ΔμH+, as an energy source. This gradient is necessary not only for ATP synthesis but also for reductive activation of CFoCF1 by thioredoxin
