Subsystem: Recycling of Peptidoglycan Amino Sugars
This subsystem's description is:
Peptidoglycan (PG) amino sugars can be recycled to resynthesize more peptidoglycan or to use as an energy source. Both free GlcNAc and anhMurNAc derived from PG are converted to GlcNAc-6-P and are thus available for reuse. As seen in the accompanying illustration, GlcNAc can be converted to UDP-GlcNAc and reenter central metabolism; enzymes responsible for these reactions are captured in other SSs. Here only the enzymes responsible for recycling the 1,6-anhydro-N-acetylmuramyl-moiety are collected.
