PrFe-mRFP1
SUMMARY
Escherichia coli strain ( DH5α ) was transformed with vector pSB1A3[http://partsregistry.org/Part:pSB1A2] containing promoters PI and PII from acidothiobacilus rus operon [http://mic.sgmjournals.org/cgi/content/abstract/150/7/2113] fused with device BBa_J04450 [http://partsregistry.org/Part:BBa_J04450] respectively , wich at 2545 bp (+) codes a monomeric red fluorescent protein mRFP1 [http://partsregistry.org/Part:BBa_E1010].

OBJECTIVES
Assemble a machine for iron detection to elucidate relation Photon (UV)-Fenton(Fe (II)) as a source of energy in extreme conditions such as Mars (ie. absence of oxigen, permanet presence of UV ligth irradiation and diferent concentratios of iron(II) as unic electron aceptor.
