From: Genetic and functional characterization of the NanA sialidase from Clostridium chauvoei
Neighbour joining tree of clostridial sialidases. The tree was constructed by ClustalW2 with gap open penalty of 10 and gap extension penalty of 0.05. The bar (0.10) represents substitutions per site. The following sialidase amino acid sequences were aligned: C. chauvoei (strain JF4135; this study), C. tertium (GenBank: CAA69951), C. sordellii (GenBank: AAB38298), C. septicum (GenBank: CAA44916), C. perfringens NanH (GenBank: P10481), C. perfringens NanI (GenBank: NP_561641) and C. perfringens NanJ (GenBank: NP_561469).
