Coordinate coverage
Mapped chains
Label and author chain identifiers are kept separately. Observed Cα counts refer to each mapped annotation core.
| Protein | Label chain | Author chain | Domain | Observed Cα / core | Observed substitutions |
|---|---|---|---|---|---|
| DNMT3A | K | ["K"] | UP:Q9Y6K1:PWWP1 | 0 / 59 | 0 |
| DNMT3A | M | ["P"] | UP:Q9Y6K1:PWWP1 | 0 / 59 | 0 |
| DNMT3B | L | ["N"] | UP:Q9UBC3:PWWP1 | 0 / 59 | 0 |
| DNMT3B | N | ["S"] | UP:Q9UBC3:PWWP1 | 0 / 59 | 0 |
