Unfortunately, the majority of the recombinant protein was present in the form of inclusion bodies (Figure 7; lanes 24), whereas its expression in the soluble fraction was low (Figure 7; lanes 57). Sisingamangaraja No.21,Kec. These enzymes have the disadvantage of being 3-phosphoadenosine 5-phosphosulfate (PAPS) dependent, which is expensive and difficult to obtain. The resulting pET-TrxA-chst11 plasmid was transformed into competent E. coli BL21 (DE3) cells which were incubated on LB-agar plates with 250g/ml ampicillin. Two bands were observed in each of the colonies (Supplementary Figure S3): one of the bands, with an approximate size of 6,000bp, corresponds to the plasmid pET32b(+); the other band, with an approximate size of 900bp, is consistent with the expected size for the chst11 gene encoding the C4ST-1 protein (892bp).
