Abstract
The invention is the discovery of an actinomycete genus, given the name Salinospora gen. nov., that displays an obligate requirement of seawater (Na+) for growth and unique 16S rRNA signature nucleotides. The invention is also the use of the genus for the production and discovery of active biomolecules such as pharmaceutical agents, agrichemicals, immunomodifiers, enzymes and enzyme inhibitors.
Claims6
A method for drug discovery comprising:
- growing a strain of actinomycete with an obligate requirement of sodium for growth, wherein the actinomycete is a strain of Salinospora comprising 16S rRNA and signature nucleotides therein, wherein the signature nucleotides are numbered and identified in accordance to the E.coli 16S rRNA sequence, wherein the residue at position 207 is adenosine;
- the residue at position 366 is cytosine;
- the residue at position 467 is uracil;
- the residue at position 468 is uracil;
- and the residue at position 1456 is guanine, in a sodium containing growth medium, wherein the strain produces a biomolecule;
- collecting the strain of Salinospora or the sodium containing growth medium containing the biomolecule;
- extracting the biomolecule from the collected strain of Salinospora or the collected sodium containing growth medium;
- and
- analyzing the biomolecule for pharmacological activity.
