Genes encoding lipid IVA acyltrasferase (msbB), biofilm formation, antimicrobial peptide resistance (carR), and 3 aminoacyl lipid modification (almEFG) have been shown to contribute to polymyxin resistance in V cholerae (6-8).
Fusidic acid has a narrower spectrum of action; it stops protein synthesis by blocking aminoacyl sRNA synthesis.
The RNA components of a ribosome are working like a ribozyme and play a central role, together with aminoacyl tRNA, in polypeptide formation, while the ribosomal proteins maintain the ribosomal structure and regulate the translational process.
Physiocrines are derived from aminoacyl tRNA synthetases, which have been known for decades to function intracellularly in protein synthesis.
Los que no contienen nitrogeno se incorporan dentro de los analogos no hidrolizables del ATP, inhibiendo enzimas intracelulares dependientes de ATP, y alterando las sintasas RNAt aminoacyl, deprimiendo la aminoacylacion del RNAt, procesos intracelulares importantes en el osteoclasto que llevan a afectar la generacion energetica celular y su sobrevida (11,12), ademas alteran el ensamblaje adecuado del citoesqueleto al romper los anillos de actina (13).
