Area around the root zone i.e. rhizosphere is a rich environment for plant growth promoting bacteria (PGPR) which can be utilized in many way to improve the growth of crop and yield. In agriculture one of the limiting factors is providing plant nutrition particularly nitrogen and phosphorus to the crop. Different Plant-Growth Promoting Rhizobacteria (PGPR) such as Azospirillum, Azotobacter, Bac...

Electron transfer (ET) proteins are biomolecules with specific functions, selected by evolution. As such they are attractive candidates for use in potential bioelectronic devices. The blue copper protein azurin (Az) is one of the most-studied ET proteins. Traditional spectroscopic, electrochemical, and kinetic methods employed for studying ET to/from the protein's Cu ion have been complemented ...

Extraction with pentane virtually abolished reduced nicotinamide adenine dinucleotide oxidase activity in small particles from Azotobacter vinelandii, but activity was largely restored by added ubiquinone.

To directly evaluate the role of increased ornithine decarboxylase (ODC) and polyamines in mouse skin carcinogenesis, we used bovine keratin 5 (K5) and keratin 6 (K6) promoter elements to direct the expression of antizyme (AZ) to specific skin cell populations. AZ is a multifunctional regulator of polyamine metabolism that inhibits ODC activity, stimulates ODC degradation, and suppresses polyam...

Ornithine decarboxylase (ODC) is a ubiquitous enzyme that is conserved in all species from bacteria to humans. Mammalian ODC is degraded by the proteasome in a ubiquitin-independent manner by direct binding to the antizyme (AZ). In contrast, Trypanosoma brucei ODC has a low binding affinity toward AZ. In this study, we identified key amino acid residues that govern the differential AZ binding a...
