Figure Legend Snippet: T5 Exo efficiently removes rcDNA and genomic DNA from DNA preparation. (A) Copies (3 × 10 8 ) of virion DNA from purified HBV virions were incubated with PSD (5 U), T5 Exo (5 U), EcoRI (5 U), or DNase I (5 U) at 37°C for 1 h and further subjected to Southern blotting. pUCX3.2 plasmid (3.2 kb) was loaded as well to indicate the positions of rcDNA and cccDNA. (B) (Top) Two micrograms of purified 3.2-kb linear HBV monomer released from the pSHH2.1 plasmid by EcoRI digestion was incubated with indicated units of T5 Exo or PSD at 37°C for 1 h. (Middle) A mixture of 3.2-kb open circular DNA (2 μg) that was artificially nicked by Nb.BtsI endonuclease and 3.2-kb supercoiled pUCX3.2 plasmid (2 μg) was subjected to T5 Exo or PSD digestion at 37°C for 1 h. (Bottom) Two micrograms of genomic DNA from uninfected HepG2 hNTCP cells was similarly treated with T5 Exo or PSD. All digestion products are shown on agarose gels, and for relative quantification, band density of untreated samples is set as 100%. (C) Copies (10 8 ) of virion DNA or pUCX3.2 plasmid were digested with T5 Exo (5 U) or PSD (5 U) in the absence (0 μg) or presence (2 μg) of genomic DNA (as shown above; 1% agarose gel) at 37°C for 1 h, and the products were loaded for Southern blotting (bottom). (D) Virion DNA (rcV) or pSHH2.1 plasmid was incubated with T5 Exo (5 U) or PSD (10 U) at 37°C for 1 h, and products were further analyzed by pp466-541 (left) or pp1040-1996 (right), respectively. ns, no significance.

Figure Legend Snippet: Detection of cccDNA and validation of Myrcludex B in 96-well plate format. (A) HepG2 hNTCP cells seeded in a 96-well plate were infected at an mge/cell of 1,000. Myrcludex B was coadministered, tenofovir was added postinoculation, and IFN-α-2a was applied during and after infection. (B) Cells were treated with each antiviral at eight doses (1:3.2 serial dilutions) in triplicates. (C) On day 7 p.i., DNA samples were extracted together using a vacuum-based system. Crude DNA in 100 μl of elute was ethanol precipitated and resuspended with 10 μl of water. T5 Exo digestion was performed prior to cccDNA quantification by PCR. HBeAg levels during days 5 to 7 p.i. in the supernatant in all wells were measured.

Figure Legend Snippet: In vitro analysis of RpnA endonuclease activity. (A) WT RpnA cleaves pUC19, RpnA-D63A does not cleave pUC19, and RpnA-D165A is more active on pUC19. The pUC19 DNA (29 nM, 50 μg/ml) is initially supercoiled but can be relaxed by nicks, linearized by double-strand cleavage, or cleaved further. The supercoiled (control), relaxed (Nb.BtsI), and linear (HindIII) forms are indicated. pUC19 was treated with RpnA-inactive RpnA-D63A or hyperactive RpnA-D165A (15 μM, 45 min). (B) Time course of an RpnA (7.5 μM)-pUC19 (29 nM) digest. Band intensity was compared to determine the relative amounts of supercoiled, nicked, and linear pUC19 at each time point. Over 90% of the supercoiled pUC19 was digested within 180 min. (C) RpnA endonuclease activity depends on divalent cation and is stimulated by Ca 2+ . The reaction buffer was 50 mM NaCl and 10 mM Tris, pH 8.0; the indicated additives were at 10 mM each. RpnA at 3.8 μM was added for 18 h. (D) RpnA cleavage products provide a DNA polymerase primer. pUC19 was digested with RpnA, DNase I, or micrococcal nuclease (MNase) to produce similar smears and then incubated with fluorescein-labeled dNTPs and the Klenow fragment of DNA polymerase. DNA was visualized by ethidium bromide (EtBr; left) or fluorescein (middle), with the two signals being merged at the right. RpnA- and DNase I-digested DNAs were effectively labeled, but micrococcal nuclease-digested DNA was not.
