Particulate membrane preparations have been isolated from cambial cells, and from differentiating and differentiated xylem cells of the main stem of pine trees. These preparations synthesise a β1→4 glucomannan from guanosine 5'-diphosphate-mannose. The polysaccharide and the synthase have been
Particulate membrane preparations isolated from cambial cells and differentiating and differentiated xylem cells of pine (Pinus sylvestris L.) trees synthesised [(14)C]glucans using either guanosine 5'-diphosphate (GDP)-D-[U-(14)C]glucose or uridine 5'-diphosphate (UDP)-D-[U-(14)C]glucose as
Our understanding of the contribution of Golgi proteins to cell wall and wood formation in any woody plant species is limited. Currently, little Golgi proteomics data exists for wood-forming tissues. In this study, we attempted to address this issue by generating and analyzing Golgi-enriched
Pinus pinaster wood samples were subjected to chemical processing for manufacturing furans and organic acids from the polysaccharide fractions (cellulose and hemicellulose). The operation was performed in a single reaction stage at 180 or 190 °C, using a microwave reactor. The reaction media
A lambda recombinant phage expressing beta-mannanase activity in Escherichia coli has been isolated from a genomic library of the extremely thermophilic anaerobe "Caldocellum saccharolyticum." The gene was cloned into pBR322 on a 5-kb BamHI fragment, and its location was obtained by deletion
Fractionation of hemicelluloses from delignified Pinus yunnanensis was carried out with KOH/H(3)BO(3) solution followed by graded precipitation in 15%, 60%, and 90% (v/v) ethanol solutions, respectively. Chemical compositions, physicochemical properties, and structures of the precipitated
Mannan polysaccharides are widespread among plants, where they serve as structural elements in cell walls, as carbohydrate reserves, and potentially perform other important functions. Previous work has demonstrated that members of the cellulose synthase-like A (CslA) family of glycosyltransferases
Samples of rice husks, Eucalyptus globulus wood and Pinus pinaster wood (containing arabinoxylan, acetylated glucuronoxylan and acetylated glucomannan as major hemicellulose components, respectively) were subjected to autohydrolysis. The resulting liquid phases, containing mainly
Genomic walking PCR was used to obtained a 4,567-bp nucleotide sequence from Caldibacillus cellulovorans. Analysis of this sequence revealed that there were three open reading frames, designated ORF1, ORF2, and ORF3. Incomplete ORF1 encoded a putative C-terminal cellulose-binding domain (CBD)
