| SPECIES IMAGE |  |
SOURCE | Jerusalem artichoke |
| LECTINS | HTA |
| MOLECULAR IMAGE |  |
CLASS | Jacalin-related lectins |
| NOMEN | LECp.Hel.Tub.tu.Hmmm1 |
| INDEX | Plant lectin / Plant / Tuber / Hololectins / Mannose/maltose-binding lectins |
| CHARACTERIZATION | A reinvestigation of Helianthus tuber lectin revealed that it is closely related to the Calystegia lectin with respect to its molecular structure and sugar specificity. |
| BIOACTIVITY | HTA agglutinates blood group A erythrocytes over other ABO groups, although all blood groups are agglutinated. See: Life Sciences 1991 (312); 573-578 |
| SOURCE TISSUE | Tuber |
| SPECIFICITY | Man/Maltose (alpha linked manno-oligosaccharides) |
| INHIBITORS | HTA is inhibited by N-acetyl-D-glucosamine, glucose, mannose, but not by galactose or N-acetyl galactosamine. |
