The O-specific polysaccharide of Proteus penneri O16 was studied by ¹H and ¹³C NMR spectroscopy, including 2D COSY, TOCSY, NOESY and H-detected ¹H,¹³C HMQC, HMQC-TOCSY and ¹H,³¹P HMQC experiments, along with chemical methods. The polysaccharide was found to be a ribitol teichoic acid-like polymer having the following structure:
