Genes encoding xylan and beta-glucan hydrolysing enzymes in Bacillus subtilis: characterization, mapping and construction of strains deficient in lichenase, cellulase and xylanase.
The gene encoding extracellular xylanase (xynA) was amplified as a 770 bp DNA fragment from Bacillus subtilis 168 chromosomal DNA by PCR. The genes encoding endo-beta-1,4-glucanase (eglS) and endo-beta-1,3-1,4-glucanase (bglS) were isolated from a genomic library of B. subtilis 168. The sequences of xynA and eglS were identical to those of the xylanase and cellulase genes from B. subtilis PAP11...
متن کاملProperties of selected hemicellulases of a multi-enzymatic system from Penicillium funiculosum.
A multi-enzymatic system from Penicillium funiculosum displayed alpha-L-arabinofuranosidase, endo-1,4-beta-D-xylanase, beta-D-xylosidase and endo-1,3-1,4-beta-D-glucanase activities at high levels over a wide acidic pH range of 2.0 to 5.5. Moreover, the pH stability was particularly extended over the wide range of pH of 2.0 to 8.0 with endo-1,3-1,4-beta-D-glucanase and endo-1,4-beta-D-xylanase;...
متن کاملMolecular and biochemical characterization of an endo-beta-1,3-glucanase from the pinewood nematode Bursaphelenchus xylophilus acquired by horizontal gene transfer from bacteria.
We report the cloning and functional characterization of an endo-beta-1,3-glucanase from the pinewood nematode Bursaphelenchus xylophilus acquired by horizontal gene transfer from bacteria. This is the first gene of this type from any nematode species. We show that a similar cDNA is also present in another closely related species B. mucronatus, but that similar sequences are not present in any ...
متن کاملCloning and DNA sequencing of xyaA, a gene encoding an endo-beta-1,4-xylanase from an alkalophilic Bacillus strain (N137).
The gene xyaA encoding an alkaline endo-beta 1,4-xylanase from an alkalophilic Bacillus sp. strain (N137) isolated in our laboratory was cloned and expressed in Escherichia coli. The nucleotide sequence of a 1,656-bp DNA fragment containing xyaA was determined, revealing one open reading frame of 993 bp that encodes a xylanase (XyaA) of 39 kDa. This xylanase lacks a typical putative signal pept...
متن کاملLic16A of Clostridium thermocellum, a non-cellulosomal, highly complex endo-beta-1,3-glucanase bound to the outer cell surface.
Clostridium thermocellum produces one major beta-1,3-glucanase. Genomic DNA fragments containing the gene were cloned from two strains, DSM1237(T) (6848 bp) and F7 (9766 bp). Overlapping sequences were 99.9 % identical. The nucleotide sequences contained reading frames for a putative transposase, endo-beta-1,3-1,4-glucanase CelC, a putative transcription regulator of the LacI type, beta-1,3-glu...
