Scientists identify proteins that help bacteria put up a fight
Date:2/25/2008

s even more potent in the resistance effort is that they can use the adapter molecule in a variety of forms to achieve membrane modification. When the researchers manipulated the tRNAs structure and properties to match differences in the molecule that would occur in different species of bacteria, the proteins could still recognize the molecule and put it to use to perform the amino acid transfer that changes the cell membrane.

This means that there is no species barrier for the spread of this virulence factor among other bacteria because this protein can recognize tRNA in any species, no matter what it looks like, Roy said.

Ibba and Roy describe their findings as only the beginning of investigating the role of the MprF family of proteins in bacteria. They believe other amino acids could also be used that would modify bacteria cell membranes, and are investigating additional pathways within the cells that lead to remodeled membranes.

We know the change to the membrane is key to resistance, Ibba said. We now know there is not just one way that can happen. We have just found a second way an organism can do this, and it is able to make the change to the membrane in two different ways. From our findings there are almost certainly even more ways that the membrane can be modified, and thats what were looking for next.
