reflectin for b.subtilis with LipA signal peptide

Constitutive promoter veg(BBa_K143012) coupled to the strong Ribosome Binding Site spoVG(BBa_K143021) from B. subtilis. These parts have been taken from 2008_Imperial_Collage. Pveg is a constitutive promoter that constitutively expresses the P43 protein in B. subtilis. SpoVG is an endogenous ribosome binding site from B. subtilis. The sequence of the spoVG ribosome binding site is AAAGGUGGUGA which is complementary to the sequence UUUCCUCCACU from the 3' region of the 16s rRNA from B. subtilis. LipA is a signal peptide from the B. subtilis genome. In general, signal peptides are responsible for directing preproteins (secretory proteins with a signal peptide region attached)through an appropriate secretory pathway[3]. LipA has been successfully used in the secretion of heterologous proteins such as cutinase by B. subtilis. Reflectin is a self-assembling protein that has the ability to reflect the sun light which depends on the thickness of the protein layer. Therefore, we thought that this ability could be used as a novel reporter for B.subtilis and E.coli.

Functional Parameters



Functional Parameters: Austin_UTexas

Burden Imposed by this Part:

Burden Value: 32.9 ± 7.8%

Burden is the percent reduction in the growth rate of E. coli cells transformed with a plasmid containing this BioBrick (± values are 95% confidence limits). This part exhibited a significant burden. Users should be aware that BioBricks with a burden of >20-30% may be susceptible to mutating to become less functional or nonfunctional as an evolutionary consequence of this fitness cost. This risk increases as they used for more bacterial cell divisions or in larger cultures. Users should be especially careful when combining multiple burdensome parts, as plasmids with a total burden of >40% are expected to mutate so quickly that they become unclonable. Refer to any one of the BBa_K3174002 - BBa_K3174007 pages for more information on the methods and other conclusions from a large-scale measurement project conducted by the 2019 Austin_UTexas team.

This functional parameter was added by the 2020 Austin_UTexas team.
