Chain D,E,F,G,H (CHTB_VIBCH | P01556)

molecular function
	GO:0046812	host cell surface binding	Interacting selectively and non-covalently with the surface of a host cell.
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
	GO:0031640	killing of cells of other organism	Any process in an organism that results in the killing of cells of another organism, including in some cases the death of the other organism. Killing here refers to the induction of death in one cell by another cell, not cell-autonomous death due to internal or other environmental conditions.
	GO:0009405	pathogenesis	The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
	GO:0006471	protein ADP-ribosylation	The transfer, from NAD, of ADP-ribose to protein amino acids.
cellular component
	GO:0005576	extracellular region	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
	GO:0033644	host cell membrane	Double layer of lipid molecules as it encloses host cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins. The host is defined as the larger of the organisms involved in a symbiotic interaction.
	GO:0020002	host cell plasma membrane	The plasma membrane surrounding a host cell.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
