Insect chitin possessing shell-like structure was prepared from the bumblebee corpses by a consequent treatment with 1M HCl and 1M NaOH. The bumblebee chitin was compared with crustacean (shrimp) chitin by using elemental analysis, Fourier-transform

Methanol accumulates in axis tissues of maturing soybean seeds, correlating with preharvest seed deterioration. Accumulation of methanol appears to be associated with the enzymic demethylation of pectin methyl esters by pectinesterase (PE; EC 3.1.1.1

Nine forms of Aspergillus sp. polygalacturonase were purified from a commercial preparation of pectinase Rohament P using chromatographies and chromatofocusing. Individual forms differ in isoelectric point, and at least five differ in structure; wher

A simple, sensitive zymogram technique for the detection of endo-polygalacturonase (EC 3.2.1.15) in gel slabs after electrophoresis or isoelectrofocusing was developed. This technique employs a new chromogenic substrate prepared by coupling D -galact

Based on strict conservation of a tyrosine residue in 24 polygalacturonases, tyrosine modification was assessed in two different forms of the Aspergillus enzyme. The second subform was unknown in structure but submitted to sequence analysis and was f

The role of histidine residues in pectinesterases was evaluated by monitoring the sensitivity to modification with diethyl pyrocarbonate in the tomato and Aspergillus niger enzymes. Different and incomplete losses of enzyme activity were obtained. In

Analysis of tomato pectinesterase by carboxymethylation, with and without reduction, shows that the enzyme has two intrachain disulfide bridges. Analysis of fragments obtained from the native enzyme after digestion with pepsin identified bridges conn
