Proper localization of chemoreceptors (MCPs) requires...?

Solution

Chemotaxis is observed in several bacteria. The chemotaxis is acheived by sensory information passed to chemoreceptors called methyl-accepting chemotaxis proteins (MCPs). These are chemoreceptors found in transmembrane. These chemoreceptors are generally arranged in hexagonal arrays. The polar clustering of chemoreceptors include histidine kinase CheA, and the adaptor protein CheW and these cause the signal amplification and adaptation. Different mechanisms are involved in polar localization of the receptors. One of the mechanisms is covalent modification of receptor. The localization of chemoreceptors is independent of phospholipid composition in the cell membrane. Methy acting chemotaxis proteins require methylation of receptos so that they are localized into the cell properly. Other mechanisms discovered include the involvement of tol - pol complex located in trans envelope of Gram negative bacteria like E. coli.
