1mwr Summary


Structure of SeMet Penicillin binding protein 2a from methicillin resistant Staphylococcus aureus strain 27r (trigonal form) at 2.45 A resolution.

The structure was published by Lim, D. and Strynadka, N.C., in 2002 in a paper entitled "Structural basis for the beta lactam resistance of PBP2a from methicillin-resistant Staphylococcus aureus." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.45 Å and deposited in 2002.

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

This PDB entry contains multiple copies of the structure of penicillin-binding protein 2a.
