Putative Cd-stress proteins YodA, YrpE and pXO1-130 share sequence similarity with adhesin AdcA

Three hypothetical stress proteins. YodA, YrpE and pXO1-130, forming a puta tive family of bacterial Cd-stress proteins, were found to exhibit sequence similarity with the 200 amino acid residues long C-terminal part of strept ococcal adhesin, AdcA, which belongs to the family 9 of extracellular solut e-binding receptors of bacteria. The sequence identity between the putative stress proteins and the C-terminal domain of adhesin is 34.2%. A weak sequ ence similarity between YodA and the N-terminal third of some bacterial cop per-binding amine oxidases recognised previously is also discussed, however , the results presented here support the idea on common functional and stru ctural features of all the three putative stress proteins and the C-termina l domain of adhesin and adhesin-like proteins.
