The Cell Wall Teichuronic Acid Synthetase (TUAS) Is an Enzyme Complex Located in the Cytoplasmic Membrane of Micrococcus luteus

Figure 6

Proposed mode of action and subcellular location for cell wall TUA biosynthesis, in which an enzyme complex, TUAS, consisting of two kinds of enzymes (Glucosyltransferase and ManNAcA-transferase), serves as a multitasking polysaccharide assembling station on the bacterial membrane for efficient elongation of cell wall teichuronic acid. Black Diamond: ManNAcA, White Circle: glucose, Rectangle: linkage oligosaccharide, and Yellow Circle: phosphate.
