Chain A,B,C,D   (WECB_ECOLI | P27828)
molecular function
    GO:0008761    UDP-N-acetylglucosamine 2-epimerase activity    Catalysis of the reaction: UDP-N-acetyl-D-glucosamine = UDP-N-acetyl-D-mannosamine.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    GO:0016853    isomerase activity    Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.
biological process
    GO:0009246    enterobacterial common antigen biosynthetic process    The chemical reactions and pathways resulting in the formation of the enterobacterial common antigen, an acidic polysaccharide containing N-acetyl-D-glucosamine, N-acetyl-D-mannosaminouronic acid, and 4-acetamido-4,6-dideoxy-D-galactose. A major component of the cell wall outer membrane of Gram-negative bacteria.
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
