Cloning and sequencing of a Bacteroides ruminicola B(1)4 endoglucanase gene

Heterologous expression of the Bacteroides ruminicola xylanase gene in Bacteroides fragilis and Bacteroides uniformis.

A cloned xylanase gene from the ruminal bacterium Bacteroides ruminicola 23 was transferred by conjugation into the colonic species Bacteroides fragilis and Bacteroides uniformis by using the Escherichia coli-Bacteroides shuttle vector pVAL-1. The cloned gene was expressed in both species, and xylanase specific activity in crude extracts was found to be at least 1400-fold greater than that foun...

Cloning, sequencing and complementation analysis of the recA gene from Prevotella ruminicola.

Degenerate PCR primers based on conserved RecA protein regions were used to amplify a portion of recA [corrected] from Prevotella ruminicola strain 23, which was used as a probe to isolate the full-length recA gene from the P. ruminicola genomic library. The P. ruminicola recA gene encoded a protein of 340 amino acids with a molecular mass of 36.81 kDa, P. ruminicola RecA was highly similar to ...

Pathway of propionate formation in Bacteroides ruminicola.

IDENTIFICATION, ISOLATION, CLONING AND SEQUENCING APARTIALANNEXIN GENE FROM AUREOBASIDIUM PULLULANS

Background and Objectives: Annexin is the common name for genes and proteins that were identified as calcium-dependent phospholipid-binding proteins. Recently a more complex set of functions has been recognized for this superfamily of proteins including in vesicle trafficking, cell division, apoptosis, calcium signalling, mineralization, crystal nucleation inside the extracellular organelle...

Cloning, sequencing, and expression of an endoglucanase gene from the rumen anaerobic fungus Neocallimastix frontalis MCH3.

A cDNA clone encoding an endo-1,4-beta-glucanase from a rumen fungus, Neocallimastix frontalis MCH3, was isolated. The nucleotide sequence showed that the gene, celA, encoded a multidomain enzyme containing a family 5 catalytic domain and a reiterated sequence that is involved in the association of a multienzyme complex, the cellulosome. The enzyme expressed in Escherichia coli showed the highe...
