ESTERASE ESTB FROM BURKHOLDERIA GLADIOLI: AN ESTERASE WITH (BETA)-LACTAMASE FOLD.

The structure was published by Wagner, U.G., Petersen, E.I., Schwab, H., and Kratky, C., in 2002 in a paper entitled "EstB from Burkholderia gladioli: a novel esterase with a beta-lactamase fold reveals steric factors to discriminate between esterolytic and beta-lactam cleaving activity" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1999.

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

This PDB entry contains multiple copies of the structure of PROTEIN (CARBOXYLESTERASE).

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 most likely forms homodimers.
