Chitinases (EC 3.2.2.14), expressed during the plant-pathogen interaction, are associated with plant defense against pathogens. In the present study, a positive correlation between chitinase activity and sugarcane smut resistance was found. ScChi (GenBank accession no. KF664180), a Class III chitinase gene, encoded a 31.37 kDa polypeptide, was cloned and identified. Subcellular localization rev...
The glycoside hydrolase family 18 chitinases degrade or alter chitin. Multiple catalytic domains in a glycoside hydrolase family 18 chitinase function synergistically during chitin degradation. Here, an insect group III chitinase from the agricultural pest Ostrinia furnacalis (OfChtIII) is revealed to be an arthropod-conserved chitinase that contains two nonsynergistic GH18 domains according to...
background and aims. class iii malocclusions are considered complex and difficult orthodontic problems to diagnose and treat. the purpose of this study was to investigate the morphologic characteristics of the craniofacial complex of adults with class iii malocclusion in an iranian population. materials and methods. lateral cephalometric radiographs of 50 patients with class iii malocclusion (2...
Background and purpose: Temporomandibular joint (TMJ) disorders are abnormalities that interfere with the shape or normal functioning of the joint, characterized by a group of clinical symptoms including pain, joint sounds, and limitation or deviation when opening the mouth. Considering the effect of skeletal relationships of the jaw on the shape, size, and morphologic variations of the condyle...
Thermostable chitinases are useful for industrial and biotechnological applications. This paper reports the stabilization of chitinase from Serratia marcescens B4A through rational mutagenesis. Changing of Ser 390 to Ile in S. marcescens. The stabilization was enhanced through entropic stabilization by reduction of the loop length and also by increasing of the beta chain length. With this repla...
The dasD gene is located just downstream of the dasABC gene cluster, encoding components of an ABC transporter for uptake of a chitin-degradation product N,N'-diacetylchitobiose [(GlcNAc)(2) ] in Streptomyces coelicolor A3(2). To clarify the roles of the DasD protein in the degradation and assimilation of chitin, we obtained and characterized a recombinant DasD protein and a dasD-null mutant of...
Proteins in the intercellular fluid (IF) of healthy Lupinus albus leaves were characterized. Silver staining of the proteins separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed more than 30 polypeptides, with the major ones having a molecular mass lower than 36 kD. After amino-terminal amino acid sequence analysis, one of the major polypeptides, IF4, was shown to hav...
