Purification, crystallization and halide phasing of a Streptococcus agalactiae backbone pilin GBS80 fragment

摘要

The C-terminal fragment of Streptococcus agalactiae (group B streptococcus) major (backbone) pilin GBS80 was purified and crystallized in two different space groups. Single-wavelength anomalous dispersion (SAD) data collected to 2.0 Å resolution on a iodide (NaI) derivative crystal using the home source were used to obtain initial phases.
