The angelic acid moiety represents an essential modification in many biologically active products. These products are commonly known as angelates and several studies have demonstrated their therapeutic benefits, including anti-inflammatory and anti-cancer effects. However, their availability for use in the development of therapeutics is limited due to poor extraction yields. Chemical synthesis has been achieved but its complexity prevents application, therefore microbial production may offer a promising alternative. Here, we engineered the budding yeast Saccharomyces cerevisiae to produce angelyl-CoA, the CoA-activated form of angelic acid. For yeast-based production of angelyl-CoA we first expressed genes recently identified in the biosynthetic cluster ssf of Streptomyces sp. SF2575 in S. cerevisiae. Exogenous feeding of propionate and heterologous expression of a propionyl-CoA synthase from Streptomyces sp. were initially employed to increase the intracellular propionyl-CoA level, resulting in production of angelyl-CoA in the order of 5 mg/L. Substituting the Streptomyces sp. propionyl-CoA carboxylase with a carboxylase derived from Streptomyces coelicolor resulted in angelyl-CoA levels up to 6.4 mg/L. In vivo analysis allowed identification of important intermediates in the pathway, including methyl-malonyl-CoA and 3-hydroxyl-2-methyl-butyryl-CoA. Furthermore, methyl-malonate supplementation and expression of matB CoA ligase from S. coelicolor allowed for methyl-malonyl-CoA synthesis and supported, together with parts of the ssf pathway, angelyl-CoA titres of approximately 1.5 mg/L. Finally, feeding of angelic acid to yeasts expressing acyl-CoA ligases from plant species led to angelyl-CoA production rates of approximately 40 mg/L. Our results demonstrate the biosynthesis of angelyl-CoA in yeast from exogenously supplied carboxylic acid precursors. This is the first report on the activity of the ssf genes. We envision that our approach will provide a platform for a more sustainable production of the pharmaceutically important compound class of angelates.

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 June 2018.
All research outputs
of 13,040,510 outputs
Outputs from Microbial Cell Factories
of 948 outputs
Outputs of similar age
of 270,371 outputs
Outputs of similar age from Microbial Cell Factories
of 1 outputs
Altmetric has tracked 13,040,510 research outputs across all sources so far. This one is in the 39th percentile – i.e., 39% of other outputs scored the same or lower than it.
So far Altmetric has tracked 948 research outputs from this source. They receive a mean Attention Score of 3.7. This one is in the 46th percentile – i.e., 46% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 270,371 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
