Fig. 3: Predicted metabolic pathways in Serratia and correspondence with historical biotyping.
a Predicted metabolic pathways across Serratia, predicted using Pathway Tools following re-annotation of assemblies using Interproscan/EggNOG-based functional annotation of representative sequences of protein groups defined by Panaroo. Shown alongside the maximum-likelihood tree in Fig. 1. b Presence/absence of selected complete metabolic pathways across Serratia marcescens. Presence of degradative pathways and that of tetrathionate reduction are coloured in blue, whilst presence of the pig gene cluster containing genes required for the biosynthesis of prodigiosin is coloured in red to reflect the red colour of this pigmented molecule. Pathways were selected according to a subset of the biochemical tests originally used to group Serratia isolates into Biotypes21 c (v, variable). d Habitat source for different S. marcescens biotypes21. Tables in c and d are adapted from Grimont and Grimont (ref. 21).
