J23101+B0034+VHb (Vitreoscilla haemoglobin)

This part is a haemoglobin isolated from Vitreoscilla (VHb) expressed behind a strong Anderson promoter and a strong RBS. VHb is a monomeric heme-containing protein that appears to improve the metabolic function of obligate aerobes and facultative anaerobes in low-oxygen conditions[3][4][5][6]. Evidence suggests that the protein binds oxygen, then shuttles it to at least one cytochrome in the electron transport chain[7], improving the rate of oxidative phosphorylation and therefore ATP production even when dissolved oxygen is scarce, resulting in increased cell metabolism. This part contains a constitute promoter and RBS ready for expression.

Expressing BBa_K1321200 in pSEVA331-Bb backbone (part BBa_K1321300) in the cellulose-producing Gluconacetobacter xylinus strain igem (part BBa_K1321306; grown at 30degC 180rpm in 5ml HS-cellulase medium, in 50ml tubes for 4 days) increases biomass production almost two-fold (see [http://2014.igem.org/Team:Imperial/Gluconacetobacter Vitreoscilla hemoglobin] on Imperial iGEM 2014 wiki for experimental data).
