CRYSTAL STRUCTURE OF ESCHERICHIA COLI TEM1 BETA-LACTAMASE AT 1.8 ANGSTROMS RESOLUTION

The structure was published by Jelsch, C., Mourey, L., Masson, J.M., and Samama, J.P., in 1993 in a paper entitled "Crystal structure of Escherichia coli TEM1 beta-lactamase at 1.8 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1993.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of BETA-LACTAMASE TEM1. This molecule has the UniProt identifier P62593 (BLAT_ECOLX)search. The sample contained 263 residues which is 100% of the natural sequence. Out of 263 residues 263 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule is most likely monomeric.
