Immunological demonstration of a unique 3,4-dihydroxyphenylacetate 2,3-dioxygenase in soil Arthrobacter strains

Article Abstract:

The common reaction in the metabolism of aromatic hydrocarbons involve the ring cleavage of vicinal dihydroxy aromatic acids with the concomitant incorporation of two atoms of molecular oxygen. An investigation was conducted to elucidate the enzymatic processes occurring in a gram-positive bacteria, Arthrobacter strain Mn-1. The results showed that Mn-1 metabolized aromatic hydrocarbons via meta cleavage through the action of 3,4-dihydroxyphenylacete 2,3-dioxygenase. Further analysis showed similar enzyme activities in 20 of the gram-positive bacteria tested, although only Arthrobacter strains exhibited antigenically related proteins.

Microbial genomics and the periodic table

Article Abstract:

Continuous research in microbial metabolism has helped in increasing awareness into how cultivated bacteria transduces chemical energy, to ultimately help growth and replication, but a lot more research needs to be done. Further research is required in the evolving age of genomics since an element required by particular bacteria may be toxic to others, thus negating research efforts.

Catabolism of arylboronic acids by Arthrobacter nicotinovorans strain PBA

Article Abstract:

Research demonstrates metabolic conversion of phenylboronic acid to phenol by Arthrobacter nicotinovorans strain PBA. The bacterium can also transform other arylboronic acids to monooxygenated products. Data indicate that the oxygen atom in the products is bound to the ring carbon atom previously bearing boronic acid substituent.
