Galactose Content

The presence of UDP-D-glucose 4-epimerase (EC 5.1.3.2) in the culture tissue of white poplar was evidenced. As found, the partially purified enzyme preparation contained UDP-D-glucose glucosyltransferase, UDP-D-galactose galactosyltransferase and non-specific enzymes able to cleave the uridine-diphosphate saccharides into the appropriate hexose monophosphates. The activity change of UDP-D-glucose 4-epimerase in tissue culture cells during the growth was in accord with changes in D-galactose content in cell walls and indicated the possibility to regulate the formation of polysaccharides containing D-galactose at the level of production of UDP-D-galactose in cells.

Galactose Content

A quantitative study was undertaken to characterize the cell walls of Arthrobacter globiformis. Varying amounts of galactose, galactosamine, glucosamine, and muramic acid were found, depending on the strain of the organism, the growth medium, and the stage of growth of the cells. The data indicated that walls obtained from pleomorphic cells are less highly polymerized than are those obtained from coccoid cells. Examination of isolated wall polysaccharide showed a wide variation in the galactose content.
