Citrus greening disease (CGD), or Huanglongbing (HLB), is principal in farming because of its severe damage, decreased yield, poor quality fruit, and frequent disappearance before harvest. Present research blended silver nanoparticles (AgNPs) colloid with chitooligomers monomers (COAMs) to create the composites referred as a “hybrid solution”. The hybrid solution has been synthesized for antimi...
Serratia proteamaculans chitinase-D (SpChiD) has a unique combination of hydrolytic and transglycosylation (TG) activities. The TG activity of SpChiD can be used for large-scale production of chito-oligosaccharides (CHOS). The multiple activities (hydrolytic and/or chitobiase activities and TG) of SpChiD appear to be strongly influenced by the substrate-binding cleft. Here, we report the unique...
To obtain an enzyme for the production of chito-disaccharides (GlcN(2)) by converting endo-chitosanase to exo-chitosanase, we chose an endo-chitosanase from Bacillus circulans MH-K1 (Csn) as the candidate for protein engineering. Using molecular modeling, two peptides with five amino acids (PCLGG) and six amino acids (SRTCKP) were designed and inserted after the positions of D(115) and T(222) o...
Chitinase A1 from Bacillus circulans WL-12 comprises an N-terminal catalytic domain, two fibronectin type III-like domains, and a C-terminal chitin-binding domain (ChBD). In order to study the biochemical properties and structure of the ChBD, ChBD(ChiA1) was produced in Escherichia coli using a pET expression system and purified by chitin affinity column chromatography. Purified ChBD(ChiA1) spe...
