Trepomonas proteins potentially involved in phagocytosis and digestion of bacterial prey. a Illustration of a Trepomonas sp. PC1 cell with phagocytosed bacteria (pink), two nuclei (blue) and eight flagella, two of which are used for motility. b Proteins predicted to have hydrolytic activity acting on the Gram-negative bacterial cell wall and membranes are indicated with scissors: glycosyltransferases (blue), bactericidal permeability-increasing proteins (black), lipidases/esterases (green), NlpC/P60 family proteins or cell wall hydrolases (red), N-acetylmuramoyl-L-alanine amidases (purple), and lysozyme family proteins (brown)
