[[2xi9]] has 2 copies of a bacterial pilus adhesin in its [[asymmetric unit]]. FirstGlance reports a putative thioester crosslink in each copy of the protein. The relevant residues are modeled as a thiester bond with correct geometry. The C-S distances in the model are 1.6 Å, in good agreement with the typical bond length of 1.7 Å<ref name="bondlengths" />. The electron density map shows clear density for the thioester-bonded atoms. The difference map (not shown) raises no alarms. The abstract of the publication highlights this thioester bond. | [[2xi9]] has 2 copies of a bacterial pilus adhesin in its [[asymmetric unit]].
