De novo methylaton of the unmethylated K. phaffii genome by human DNA methyltransferases (DNMTs) [RNA-seq]

ABSTRACT: We engineered combinatorial knock-in of human DNMTs in Komagataella phaffii, a yeast species lacking endogenous DNA methylation, to characterize methylation preferences and functional consequences of individual de-novo DNMTs as well as their combinations. Methylation preferences were determined through whole-genome bisulfite sequencing (WGBS) experiments. Effects of knock-in on gene expression were determined by RNA-seq. Measurements of genome-wide methylation produced by distinct de-novo DNMTs permitted determination of methylation preferences and aversions specific to individual DNMTs. Combining methylation and gene expression data provided insight about cellular response to the stress of DNA methylation and about the association between gene methylation patterns and changes in transcriptional output.
