Publication Abstract from PubMedThe structure of the BA42 protein belonging to the Antarctic flavobacterium Bizionia argentinensis was determined by Nuclear Magnetic Resonance and X-ray crystallography. This is the first structure of a member of the PF04536 family comprised of a stand-alone TPM domain. The structure reveals a new topological variant of the four beta-strands constituting the central beta-sheet of the alphabetaalpha architecture and a double metal binding site stabilizing a pair of crossing loops, not observed in previous structures of proteins belonging to this family. BA42 shows differences in structure and dynamics in the presence or absence of bound metals. The affinity for divalent metal ions is close to that observed in proteins that modulate their activity as a function of metal concentration, anticipating a possible role for BA42.
