Journal ArticleDOI
A lectin with mitogenic activity from the edible wild mushroom Boletus edulis
TL;DR: The lectin stimulated the mitogenic response of mouse splenocytes attaining a maximum at 1 μM, and inhibited human immunodeficiency virus-1 reverse transcriptase with an IC50 of 14.3 μM, but did not exhibit antifungal activity.
Journal ArticleDOI
Marine lectins and their medicinal applications.
TL;DR: Recent research on the isolation and identification of marine lectins with potential value in medicinal applications is reviewed, finding that many of them have not yet been extensively studied when compared with their terrestrial counterparts.
Journal ArticleDOI
Lunatusin, a trypsin-stable antimicrobial peptide from lima beans (phaseolus lunatus l.)
John Wong,Tzi Bun Ng +1 more
TL;DR: Lunatusin exerted an anti-fungal activity toward fungal species such as Fusarium oxysporum, Mycosphaerella arachidicola and Botrytis cinerea, and an antibacterial action on Bacillus megaterium, Bacillus subtilis, Proteus vulgaris and Mycobacterium phlei.
Journal ArticleDOI
Demonstration of ribonuclease activity in the plant ribosome-inactivating proteins alpha- and beta- momorcharins
TL;DR: Using polyhomoribonucleotides as substrate, it was found that the momorcharins preferentially acted on polyU, but exerted negligible effects on polyA, polyC and polyG, suggesting that the enzymatic action involved ribonucleolytic cleavage.
Journal ArticleDOI
Cloning of the cDNA of alpha-momorcharin: a ribosome inactivating protein.
TL;DR: Examination of the predicted secondary structure of α-momorcharin and trichosanthin indicates that these proteins have regions of high structural similarities and this may account for the common biological activities that they share, viz., abortificant, immunosuppressive, antitumor and inhibition of HIV-1.
