Team:Davidson-Missouri Western/XOR and Autoinducers

Signal molecules
These signaling molecule were used in the cellular communication systems we used in this project to regulate the activity of certain promoter activation proteins in the hybrid promoters we designed and built.



Gram (-) bacteria use:

3-oxo-C6-HSL, N-(3-oxohexanoyl)-L-homoserine lactone, an AHL

DPD, the AI-2 precursor, 4,5 dihydroxy-2,3-pentanedione

HHQ, 2-heptyl-4(1H)-quinolone, an AQ

Gram (+) bacteria use:

DPD, the AI-2 precursor, 4,5 dihydroxy-2,3-pentanedione

A-Factor, 2-isocapryloyl-3-hydroxymethyl--butyrolactone

PQS, pseudomonas quinolone signal, 2-heptyl-3-hydroxy-4(1H)-quinolone

DSF, ‘diffusible factor’, cis-11-methyl-2-dodecenoic acid

3OH-PAME, hydroxyl-palmitic acid methyl ester;

AIP-1, staphylococcal autoinducing peptide 1
