Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.
ad-work [718]

True. Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.

A significant resistance mechanism in Gram-negative bacteria is drug efflux. It expel solutes from the cell. Antimicrobials and metabolites are just a few of the hazardous compounds that Efflux pumps help bacteria remove from their interior environments so they can regulate it.

The main efflux systems in Gram-negative bacteria are members of the RND superfamily and typically consist of an outer membrane protein channel, a periplasmic protein, and a cytoplasmic membrane pump. The most common example is  MFS (such as Bmr and Blt in Bacillus subtilis) and the ABC transporters.

Given the names of these three enzymes proteases, DNase, RNase what reaction do you expect each one to catalyze
kramer

Answer:

As the name suggests, proteases will be the enzymes which will catalyze the reactions of proteolysis. Proteolysis can be described as the process of breaking proteins into amino acids and simple peptide bonds.

DNases will catalyze the reactions for breaking down or degrading DNA. The DNase does this by breaking the phosphodiester bonds present in the backbone of the DNA.

RNases will be the enzymes which will catalyze the breaking of RNA molecules.
