Iâm way late with this on March 9th but Iâve watched Paul Kangas for years! He has always epitomized the NBR to me and I will sorely miss him. He was always sharp and crisp and on point.
the bacterial cytoskeleton and cell shape-determining proteins such as MreC, function in concert to orches-trate the localization of cell wall synthetic complexes resulting in spatially co-ordinated and efficient pepti-doglycan synthetic activity. Introduction The distinct morphology of most bacterial cells is dictated by the architecture of the peptidoglycan cell wall. In Gram-negative bacteria, the cell wall is thought to be a single
In order to protect the bacterial genomic DNA from its own restriction enzymes, bacterial cells employ a system, wherein methyl transferases methylate certain bases on the DNA â¦ sequence, making them unrecognizable to the restriction enzymes. Each restriction enzyme has a methylase associated with it on the chromosome. This methylase puts methyl groups on the host DNA, and the restriction enzyme doesn't recognize its recognition sequence when it is so methlyated. The host DNA is thus protected from the actions of its own restriction enzyme.
