Double mutant PBP2x T338A/M339F from Streptococcus pneumoniae strain R6 at 2.4 A resolution

The structure was published by Chesnel, L., Pernot, L., Lemaire, D., et al., Dideberg, O., Vernet, T., and Zapun, A., in 2003 in a paper entitled "The Structural Modifications Induced by the M339F Substitution in PBP2x from Streptococcus pneumoniae Further Decreases the Susceptibility to beta-Lactams of Resistant Strains" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.42 Å and deposited in 2003.

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

The PDB entry contains the structure of Penicillin-binding protein 2X. This molecule has the UniProt identifier P59676 (PBPX_STRR6)search. The sample contained 702 residues which is 94% of the natural sequence. Out of 702 residues 606 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.
