AbstractIsopentenyl diphosphate isomerase (IDI, EC 5.3.3.2) catalyzes the revisable conversion of 5-carbon isopentenyl diphosphate and its isomer dimethylallyl diphosphate, which are the essential precursors for isoprenoids, including carotenoids. Here we report on the cloning and characterization of a novel cDNA encoding IDI from sweet potato. The full-length cDNA is 1155 bp with an ORF of 892 bp encoding a polypeptide of 296 amino acids, which was designated as IbIDI (GenBank Acc. No: DQ150100). The computational molecular weight is 33.8 kDa and the theoretical isoelectric point is 5.76. The deduced amino acid sequence of IbIDI is similar to the known plant IDIs. The tissue expression analysis revealed that IbIDI expressed at higher level in sweet-potato’s mature leaves and tender leaves than that in tubers, meanwhile, no expression signal could be detected in veins. Recombinant IbIDI was heterologously expressed in engineered Escherichia coli which led to the reconstruction of the carotenoid pathway. In the engineered E. coli, IbIDI could take the role of Arabidopsis IDI gene to produce the orange β-carotene. In summary, cloning and characterization of the novel IDI gene from sweet potato will facilitate our understanding of the molecular genetical mechanism of carotenoid biosynthesis and promote the metabolic engineering studies of carotenoid in sweet potato.

Abstract Background Pinene is a monoterpene, that is used in the manufacture of fragrances, insecticide, fine chemicals, and renewable fuels. Production of pinene by metabolic-engineered microorganisms is a sustainable method. Purple non-sulfur photosynthetic bacteria belong to photosynthetic chassis that are widely used to synthesize natural chemicals. To date, researches on the synthesis of pinene by purple non-sulfur photosynthetic bacteria has not been reported, leaving the potential of purple non-sulfur photosynthetic bacteria synthesizing pinene unexplored. Results Rhodobacter sphaeroides strain was applied as a model and engineered to express the fusion protein of heterologous geranyl diphosphate synthase (GPPS) and pinene synthase (PS), hence achieving pinene production. The reaction condition of pinene production was optimized and 97.51 μg/L of pinene was yielded. Then, genes of 1-deoxy-d-xylulose 5-phosphate synthase, 1-deoxy-d-xylulose 5-phosphate reductoisomerase and isopentenyl diphosphate isomerase were overexpressed, and the ribosome binding site of GPPS-PS mRNA was optimized, improving pinene titer to 539.84 μg/L. Conclusions In this paper, through heterologous expression of GPPS-PS, pinene was successfully produced in R. sphaeroides, and pinene production was greatly improved by optimizing the expression of key enzymes. This is the first report on pinene produce by purple non-sulfur photosynthetic bacteria, which expands the availability of photosynthetic chassis for pinene production.

ABSTRACT Putative hopanoid genes from Streptomyces peucetius were introduced into Escherichia coli to improve the production of squalene, an industrially important compound. High expression of hopA and hopB (encoding squalene/phytoene synthases) together with hopD (encoding farnesyl diphosphate synthase) yielded 4.1 mg/liter of squalene. This level was elevated to 11.8 mg/liter when there was also increased expression of dxs and idi, E. coli genes encoding 1-deoxy-d-xylulose 5-phosphate synthase and isopentenyl diphosphate isomerase.
