Application
Glutamate racemase has emerged as a potential antibacterial target since the product of this enzyme, D-glutamate, is an essential component of bacterial walls. Inhibiting the enzyme will prevent bacterial wall formation and ultimately result in lysis of the bacteria cell by osmotic pressure. Furthermore glutamate racemase is not expressed nor is the product of this enzyme, D-glutamate is normally found in mammals, hence inhibiting this enzyme should not result in toxicity to the mammalian host organism. Possible inhibitors to MurI includes aziridino-glutamate that would alkylate the catalytic cysteines; N-hydroxy glutamate that by mimicking Wat2 (the bound water molecule that interacts with glutamate amino group) would prevent binding of the substrate; or 4-substituted D-glutamic acid analogs bearing aryl-, heteroaryl-, cinnamyl-, or biaryl-methyl substituents that would also prevent binding of substrate.

Famous quotes containing the word application:
“There are very few things impossible in themselves; and we do not want means to conquer difficulties so much as application and resolution in the use of means.”
—François, Duc De La Rochefoucauld (1613–1680)
““Five o’clock tea” is a phrase our “rude forefathers,” even of the last generation, would scarcely have understood, so completely is it a thing of to-day; and yet, so rapid is the March of the Mind, it has already risen into a national institution, and rivals, in its universal application to all ranks and ages, and as a specific for “all the ills that flesh is heir to,” the glorious Magna Charta.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“The human mind is capable of excitement without the application of gross and violent stimulants; and he must have a very faint perception of its beauty and dignity who does not know this.”
—William Wordsworth (1770–1850)
