Abstract
In this study, we purified a lectin isolated from the seeds of Dioclea bicolor (DBL) via affinity purification. Electrophoresis analysis revealed that DBL had three bands, α, β, and γ chains, with molecular masses of approximately 29, 14, and 12 kDa, respectively. Gel filtration chromatography revealed that the native form of DBL had a molecular mass of approximately 100 kDa, indicating that it is a tetramer. Interestingly, DBL-induced hemagglutination was inhibited by several glucosides, mannosides, ampicillin, and tetracycline with minimum inhibitory concentration (MIC) values of 1.56-50 mM. Analysis of the complete amino acid sequence of DBL revealed the presence of 237 amino acids with high similarity to other Diocleinae lectins. Circular dichroism showed the prominent β-sheet secondary structure of DBL. Furthermore, DBL structure prediction revealed a Discrete Optimized Protein Energy (DOPE) score of -26,642.69141/Normalized DOPE score of -1.84041. The DBL monomer was found to consist a β-sandwich based on its 3D structure. Molecular docking showed the interactions between DBL and α-D-glucose, N-acetyl-D-glucosamine, α-D-mannose, α-methyl-D-mannoside, ampicillin, and tetracycline. In addition, DBL showed antimicrobial activity with an MIC of 125 μg/mL and exerted synergistic effects in combination with ampicillin and tetracycline (fractional inhibitory concentration index ≤ 0.5). Additionally, DBL significantly inhibited biofilm formation and showed no toxicity in murine fibroblasts (p < 0.05). These results suggest that DBL exhibits antimicrobial activity and works synergistically with antibiotics.

Abstract
A seed lectin from Manilkara zapota (MZSL) was purified using ammonium sulphate precipitation and affinity chromatography. Hemagglutination activity, neutral sugar content and physicochemical properties of the lectin were determined and toxicity was checked by brine shrimp toxicity assay. Antimicrobial, antioxidant as well as in vitro anticancer activities of MZSL were also evaluated. Our findings showed the molecular weight of MZSL to be 33.0 ± 1 kDa. Minimum hemagglutination concentration of the lectin was 15.625 μg/ml. With a neutral sugar content of 6.32 %, the lectin was fully active at a temperature range of 30-50 °C and pH 7.0-8.0 and it was mildly toxic with an LC50 value of 107.93 μg/ml. The lectin demonstrated bacteriostatic activity against gram-positive bacteria in contrast to gram-negative bacteria at a concentration of 31.25 μg/ml, agglutinated Staphylococcus aureus and Shigella dysenteriae and exerted fungistatic activity against Aspergillus niger. MZSL dose-dependently reduced the formation of biofilm by E. coli. DPPH assay confirmed its antioxidant activity with an IC50 value of 96.42 μg/ml. MZSL showed 21.64 % growth inhibition against Ehrlich ascites carcinoma (EAC) cells at 80 μg/ml whereas its antiproliferative potential against MCF-7 and A-549 cancer cell lines became evident with IC50 values of 70.66 μg/ml and 107.64 μg/ml, respectively.

Abstract
The resistance of micro-organisms to antimicrobial agents has been a challenge to treat animal and human infections, and for environmental control. Lectins are natural proteins and some are potent antimicrobials through binding to carbohydrates on microbial surfaces. Oligomerization state of lectins can influence their biological activity and maximum binding capacity; the association among lectin polypeptide chains can alter the carbohydrate-lectin binding dissociation rate constants. Antimicrobial mechanisms of lectins include the pore formation ability, followed by changes in the cell permeability and latter, indicates interactions with the bacterial cell wall components. In addition, the antifungal activity of lectins is associated with the chitin-binding property, resulting in the disintegration of the cell wall or the arrest of de novo synthesis from the cell wall during fungal development or division. Quorum sensing is a cell-to-cell communication process that allows interspecies and interkingdom signalling which coordinate virulence genes; antiquorum-sensing therapies are described for animal and plant lectins. This review article, among other approaches, evaluates lectins as antimicrobials.
