MreB Perturbing Compound A22 is primarily used in microbiological research to study bacterial cell morphology and cytoskeleton dynamics. It inhibits the function of MreB, a protein crucial for maintaining the rod shape of many bacteria. By disrupting MreB, A22 causes bacterial cells to lose their typical elongated form, often becoming spherical. This property makes it a valuable tool for investigating the role of the bacterial cytoskeleton in cell shape determination, division, and growth. Researchers also use A22 to explore potential antibacterial strategies, as its ability to alter cell morphology can compromise bacterial survival and virulence. Its application extends to understanding the mechanisms of antibiotic resistance and identifying new drug targets in pathogenic bacteria.
