Fluorosugar donors disrupt the alternating linkage pattern and terminate polymerization. GlfT2 can elongate acceptor 12 by one residue when donor 2 is supplied (A, top), or by two residues when donor 3 is used (A, bottom). MALDI-TOF traces show chain termination is a result of pattern disruption (B).
