AMINO TERMINAL DOMAIN OF ENZYME I FROM ESCHERICHIA COLI

The structure was published by Liao, D.I., Silverton, E., Seok, Y.J., Lee, B.R., Peterkofsky, A., and Davies, D.R., in 1996 in a paper entitled "The first step in sugar transport: crystal structure of the amino terminal domain of enzyme I of the E. coli PEP: sugar phosphotransferase system and a model of the phosphotransfer complex with HPr." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1996.

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