Part:BBa_K2213005
PduD(1-20)_mCherry_cgPPK2_His6
Figure 1: The overall architecture of the construct
The PduD(1-20) domain is sufficient to localise the part into a recombinant ethanolamine utilisation (Eut) or 1, 2 propanediol (Pdu) bacterial microcompartment (Jakobson et al., 2015). The mCherry allows monitoring the subcellular location of the part. The cgPPK2 domain encodes a soluble class II polyphosphate kinase from Corynebacterium glutamicim with a specific activity 30-fold greater than that of E. coli(Lindner et al., 2007;Kornberg and Simms, 1956). The part also contains a C-terminal hexa-histidine tag to allow purification with immobilised metal ion affinity chromatography.
The part was overexpressed in a BL21 (DE3) strain of E. coli under the control of a T7 promoter and purified to a certain degree (Figure 1)
