| Extraction protocol |
DNA was purified using Qiagen's Puregene kit and sonicated to about 200 bp.
Fragmented DNA was purified by Zymo DNA Clean and Concentration Kit. Then, the selective 5hmC chemical labeling was performed in glucosylation buffer (50 mM HEPES buffer pH 8.0, 25 mM MgCl2) containing above fragmented DNA, βGT, N3-UDP-Glc, and incubated at 37°C for 2 hr. After DNA purification in ddH2O, DBCO-PEG4-Biotin (Click Chemistry Tools) was added and incubated at 37°C for 2 hr. The biotin labeled DNA was pulled down by C1 Streptavidin beads (Life Technologies) for 15 min at room temperature. Next, the captured DNA fragments were subjected to PCR amplification using Nextera DNA sample preparation kit. The resulting amplified product was purified by 1.0X AMPure XP beads. Input library was made by direct PCR from fragmented DNA directly without labeling and pull-down. The libraries were quantified by a Qubit fluorometer (Life Technologies) and sequenced on NextSeq 500.

| Data processing |
Sequencing reads were trimmed of low quality nucleotides by trim_galore.
High-quality reads were then mapped to hg19 reference genome by Bowtie with uniquely mapped reads retained for the following analyses.
PCR duplicates were removed by Samtools.
Normalization were performed by Deeptools.
Peak calling was performed with MACS2.
