An RNA sequencing data set revealing differentially expressed transcripts during ε-poly-L-lysine production in Streptomyces albulus.


ABSTRACT: Purpose: Streptomyces albulus is an industrial producer of ε-poly-L-lysine, an antimicrobial cationic homo poly-amino acid used practically as a natural food preservative. Here, we present RNA sequencing data set unveiling differentially expressed transcripts during ε-poly-L-lysine production in the most extensively studied poly-L-Lys producer, S. albulus NBRC14147. Methods: During the poly-L-Lys fermentation, cells grown for 8 hours and 35 hours were harvested as growth phase cells and production phase cells, respectively, and total RNA were extracted individually. A 100-bp paired-end mRNA sequencing was performed for each sample on the Illumina HiSeq 2500 system. Result: Using an optimized data analysis workflow, we were able to map more than 44 million sequence reads per sample to the reference genome (GenBank accession number ASM385166v1). Differential gene expression analysis was performed using the edgeR. The RNA-seq data revealed that a total of 2449 genes were considered to be differentially expressed during poly-L-Lys production using a fold change cutoff of log2 less than -1 and greater than 1 (equivalent to a ±2-fold change). Conclusion: Our data will serve as a primary source for investigating the regulatory mechanism which govern poly-L-Lys production in S. albulus NBRC14147.
