Furthermore, an estimation of UTI-CS chain length was performed as the ratio between the moles of disaccharides and the moles of UTI, considering 15.974 kDa as UTI molecular weight calculated through ExPASy Compute pI/Mw tool (http://www.expasy.org), according to the sequence reported by Xu et al. [45]. The gene discussed is CS; the disease is bacterial urinary tract infection.
