Schizosaccharomyces pombe is a simple unicellular organism that is closer to mammalian cells than brewer's yeast. S. pombe combines the use of synthetic biology-based strategies and methods to efficiently produce a wide range of high-value-added products such as biofuels, biomaterials, bulk chemicals, fine chemicals, pharmaceuticals and their intermediates, and rare natural and non-natural products.
As a company specializing in the field of biology, CD BioGlyco provides high-quality S. pombe engineering services by constructing Chassis Cell Platforms.
Endogenous and heterologous promoter sequences with higher transcriptional potency, specificity, and the ability to achieve precise regulation (quantitative, timed, and targeted) can effectively increase the yield of heterologous proteins as well as other products synthesized by the S. pombe system (chassis cells). CD BioGlyco provides the development of promoters for the S. pombe system according to client needs.
Development of shorter sequences and stronger promoters by artificial systematic modifications
Enhancement of promoter activity by appropriate genetic modification and modification of existing promoters
Meanwhile, based on the excellent performance promoter, we construct more different types of S. pombe gene expression vectors to further enhance the efficiency of synthesized products in S. pombe chassis cells.
CD BioGlyco offers several methods to construct expression vectors for S. pombe.
Screening of integrating plasmids
Screening of S. pombe centromere sequence
Screening of S. pombe autonomously replicating sequence
Gene engineering is an effective means of improving the productivity of the S. pombe system. CD BioGlyco offers a variety of gene editing tools to choose from.
Cre-loxP system
Cre-loxP system mainly consists of Cre recombinase and loxP sites, which can be used to genetically modify or alter the target genes on the chromosome by utilizing the principle that Cre recombinase can specifically recognize loxP sites. Cre-loxP system is not only capable of knocking out or replacing individual genes but also efficiently completing the one-time knockout of multiple genes.
CRISPR-Cas system
The CRISPR-Cas system is an RNA-guided technology that utilizes a special nuclease such as Cas9 to perform targeted editing of target genes on S. pombe chassis cells. Compared with the traditional gene editing methods, the CRISPR-Cas system is easier to operate, and it only needs to synthesize a sgRNA to achieve specific modifications of the target gene.
In addition, we have meganucleases and transcription activator-like effector nucleases to enable gene editing of S. pombe chassis cells.

Results: In this research, the authors successfully developed a metabolic engineering of S. pombe to enhance 3-hydroxypropionic acid (3-HP) production from glucose and cellobiose via the malonyl coenzyme A pathway. To increase the cellular supply of malonyl coenzyme A and acetyl coenzyme A, the authors introduced genes encoding endogenous aldehyde dehydrogenase, acetyl coenzyme A synthase from Salmonella enterica, and endogenous pantothenate kinase into S. pombe. The authors also engineered sugar supply by demonstrating β-glucosidase (BGL) on the surface of yeast cells. Eventually, the authors succeeded in obtaining a high yield of 3-HP at a glucose concentration of 50 g/L.
