Biosynthesis of the Bacterial Cell Wall Peptidomurein

Sucrose-6 -phosphate is biosynthesized in the leaves of plants and acts as a transport sugar in plants. In sugarcane it is transported into the stems where su-crose-6 -phosphate phosphatase hydrolyzes the phosphate group allowing the deposit of sucrose (cane sugar). In sugar beets the sucrose-6 -phosphate is transported to the tubers where the same kinds of reactions occur to deposit sucrose. 

In 1949, Park and Johnson [36] observed the accumulation of large amounts of uridine diphospho sugars in the cultures of Staph aureus that had been treated with penicillin. The structures of these compounds were unknown and they were called the Park-Johnson compounds. Much later they were shown to be UDP-
