  • a Proteins were grouped for convenience based on (i) whether the non-PTS domains were partial domains (categories A to E) or full-length domains (categories Fand G) and (ii) whether the non-PTS domain was in the middle (category A), at the C terminus (categories B and F), or at the N terminus (categories C to E) of the protein. While category C includes proteins with non-PTS domains fused N-terminally to PTS enzyme IIA or IIB, category D includes N-terminal fusions of non-PTS domains to the PTS enzyme IIC; category E is a miscellaneous group of fusion proteins.
