Cloning and Sequencing of the Levansucrase Gene from Acetobacter xylinum NCI 1005

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...

Survey on Nano-fibers from Acetobacter Xylinum

The structure of novel C35 pentacyclic terpenes from Acetobacter xylinum.

A novel C(35) terpene and its monounsaturated analogue were isolated from cultures of Acetobacter xylinum, together with traces of their C(36) homologues. These substances were found to be hopane derivatives substituted by a five-carbon chain bearing four vicinal hydroxyl groups. For the parent hydrocarbon the term bacteriohopane is proposed. The elucidation of the structures utilized high-reso...

Synthesis of Cellulose by Acetobacter Xylinum

Appearance of cellulose microfibrils in the medium of a suspension of cells of Acetobacter xylinum in buffered glucose solution was preceded by a stage during which the cellulose in the medium was amorphous within the available resolution. The size of the vertical axis of the microfibrils of the bacterial cellulose was found on the basis of measurement of shadow length to be only about 16 A. In...

Partial Cloning and Nucleotide Sequencing of Glutamate Decarboxylase Gene Isoform 65 from Human Brain

Background: Gamma -aminobutyric acid (GABA), a non-protein amino acid acts as an inhibitory neurotransmitter in the central nervous system of mammalians. The glutamate decarboxylase (GAD) is responsible for the conversion of L-glutamate to GABA. The human brain has two isoforms of this enzyme, GAD65 and GAD67 that differ in molecular weight, amino acid sequence, antigenicity, cellular location ...
