Preparation of chitooligosaccharide from fungal waste mycelium by recombinant chitinase [PDF]

, 2016
This study aimed to develop an enzymatic method for conversion of chitin from fungal waste mycelia to chitooligosaccharides. The recombinant chitinase LlChi18A from Lactococcus lactis was over-expressed by Escherichia coli BL21 (DE3) and purified by ...

Overexpression of chitinase PbChia1 from Plasmodiophora brassicae improves broad-spectrum disease resistance of Arabidopsis

Virulence, 2023
Chitinase plays an important role in plant resistance against chitin-containing pathogens through hydrolysis of chitin. Clubroot caused by Plasmodiophora brassicae is a major disease for cruciferous crops and vegetables worldwide.

Characterization of Extracellular Chitinase from Bacterial Isolate 99 and Enterobacter sp. G-1 from Matsue City, Japan

Microbiology Indonesia, 2010
One hundred and twenty isolates of chitosanase producing bacteria were screened from water and soil from localies around Matsue city, Japan. In previous experiments, four isolates (isolates 96, 97, 99, and 100 strain ) were analyzed for their chitosanase

CHI3L1 polymorphisms, cord blood YKL-40 levels and later asthma development [PDF]

, 2016
Single nucleotide polymorphisms (SNPs) in chitinase 3-like 1 (CHI3L1), the gene encoding YKL-40, and increased serum YKL-40 levels are associated with severe forms of asthma. It has never been addressed whether SNPs in CHI3L1 and cord blood YKL-40 levels

Targeting CD300a Signaling With a Phosphatidylserine‐Presenting Hydrogel Rescues Macrophage Dysfunction and Accelerates Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the proposed mechanism: PEG/RGD‐PSLs mimic apoptotic cells to engage PS receptors (notably CD300a), transducing an inhibitory signal that suppresses the MyD88/NF‐κB pathway, leading to global anti‐inflammatory and pro‐reparative effects.
