The Neisserial Phage-associated Holin -LRB- NP-Holin -RRB- Family -LRB- TC # 1 .. E. 22 -RRB- is a family of small proteins , between 47 - 53 amino acyl residues in length , that exhibit a single N-terminal transmembrane segment -LRB- TMS -RRB- .. N-terminal. N-terminus. Although annotated as phage proteins or holins , NP-Holin proteins are not yet functionally characterized , thus more research is needed to confirm holin activity .. phage. Bacteriophage. A representative list of proteins belonging to the NP-Holin family can be found in the Transporter Classification Database .
