+== Publication Abstract from PubMed ==
+Catabolite control protein A (CcpA) functions as master transcriptional regulator of carbon catabolism in Firmicutes. It belongs to the family of bacterial repressor/regulator proteins. Here, the crystal structure of the 76 kDa homodimeric CcpA protein from Lactococcus lactis subsp. lactis IL1403 is presented at 1.9 A resolution in the absence of cognate DNA. The phases were derived by molecular replacement and the structure was refined to crystallographic R and R(free) factors of 0.177 and 0.211, respectively. The presence of a sulfate molecule in the direct vicinity of a putative effector-binding site in the monomer allowed the derivation of a model for the possible binding of small organic effector molecules.
