Function
Beta-glucosyltransferase is an enzyme, or more specifically an inverting glycosyltransferase(GT). In other words it transfers glucose from uridine diphospho-glucose (UDPglucose)to an acceptor, modified DNA through beta-Glycosidic bond. The role of the enzyme is to protect the infecting viral DNA from the bacteria's restriction enzymes. Glucosylation prevents the virus DNA from being cut up. Furthermore, glucosylation may aid gene expression of the bacteriophage by influencing transcription.

Famous quotes containing the word function:
“It is the function of vice to keep virtue within reasonable bounds.”
—Samuel Butler (1835–1902)
“As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.”
—Adam Phillips, British child psychoanalyst. “Worrying and Its Discontents,” in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)
“It is not the function of our Government to keep the citizen from falling into error; it is the function of the citizen to keep the Government from falling into error.”
—Robert H. [Houghwout] Jackson (1892–1954)
