Crystal Structure of UDP-N-acetylmuramic acid:L-alanine ligase (MurC) in Complex with UMA and ANP.

The structure was published by Mol, C.D., Brooun, A., Dougan, D.R., et al., Knuth, M.W., McRee, D.E., and Swanson, R.V., in 2003 in a paper entitled "Crystal Structures of Active Fully Assembled Substrate- and Product-Bound Complexes of UDP-N-Acetylmuramic Acid:L-Alanine Ligase (MurC) from Haemophilus influenzae." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 2003.

The experimental data on which the structure is based was not deposited.
