This unique feature of FK506 biosynthesis, in which a dedicated PKS provides an atypical extender unit for the main modular PKS, illuminates a new strategy for the combinatorial biosynthesis of designer macrolide scaffolds as well as FK505 analogues.
The dynamic transcriptional and translational landscape of the model antibiotic producer Streptomyces coelicolor A3(2)
Nucleotide resolution genome-scale measurements of the transcriptome and translatome of Streptomyces coelicolor, the model antibiotic-producing actinomycete, are integrated and it is revealed that the translation efficiency of secondary metabolic genes is negatively correlated with transcription and that several key antibiotic regulatory genes are translationally induced at transition growth phase.

Results show that the methylmalonyl-CoA supply is a limiting factor for FK506 biosynthesis and that among the three pathways analyzed, the MCM pathway is the most effective precursor supply pathway supporting the highest titer of Fk506 in S. clavuligerus CKD1119.
Roles of fkbN in Positive Regulation and tcs7 in Negative Regulation of FK506 Biosynthesis in Streptomyces sp. Strain KCTC 11604BP
Semiquantitative reverse transcription-PCR analyses of the transcription levels of the FK506 biosynthetic genes in the wild-type and mutant strains proved that most of the fkbN encodes a positive regulatory protein essential for Fk506/FK520 biosynthesis and that the gene product of tcs7 negatively regulates their biosynthesis, demonstrating the potential of exploited for strain improvement.
Immobilization of Horseradish Peroxidase on Multi-Wall Carbon Nanotubes and its Electrochemical Properties
Horseradish peroxidase (HRP) was immobilized on carboxylated multi-wall carbon nanotubes in the presence of a coupling reagent, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide. The immobilized HRP…
Generation of multiple bioactive macrolides by hybrid modular polyketide synthases in Streptomyces venezuelae.
A Review of the Microbial Production of Bioactive Natural Products and Biologics
The structures and diverse biological activities of natural products and recombinant proteins that have been exploited as valuable molecules in medicine, agriculture and insect control are introduced and suggested to inspire the development of new therapeutic agents in academia and industry.
Discovery of parallel pathways of kanamycin biosynthesis allows antibiotic manipulation.
It is discovered that the kanamycin biosynthetic pathway contains an early branch point, governed by the substrate promiscuity of a glycosyltransferase, that leads to the formation of two parallel pathways in which early intermediates are further modified.
