Biological function
Heat-labile enterotoxin (LT) is a hetero-oligomeric AB 5 type enterotoxin composed of a 27 kDa A subunit with toxic ADP ribosyl transferase activity and a stable noncovalent-linked pentamer of 11.6 kDa B subunits.

The B subunit pentamer mediates holotoxin binding to ganglioside GM1 on intestinal epithelial cells, with lower affinity for GD1B, asialoGM1 and lactosylceramide gangliosides.
