Fig. 4BSequence alignment of DUF3055-containing proteins and dimer structure of SAV0927. (A) Conserved amino acid sequences are highlighted. The DUF3055 domain is indicated above the sequences. a for DUF3055 containing protein (SAV0927) from Staphylococcus aureus; b from Staphylococcus edaphicus; c from Bacillus azotoformans MEV2011; d from Thermobacillus composti KWC4; e from Brevibacillus sp. CF112; f from Paenibacillus aceti. The asterisk marks above the amino acids indicate the residues involved in interaction between the adjacent dimers (see ). (B) N-terminus and C-terminus are represented respectively at chain C (green arrow) and chain D (grey arrow) of SAV0927.
