four-way junction helicase activity

Unwinding a DNA helix of DNA containing four-way junctions, including Holliday junctions, driven by ATP hydrolysis.

pyrimidine dimer repair

The repair of UV-induced T-T, C-T and C-C dimers.

heart contraction

The multicellular organismal process in which the heart decreases in volume in a characteristic way to propel blood through the body.

protein-RNA adaptor activity

The binding activity of a protein that brings together another protein and an RNA, permitting those molecules to function in a coordinated way.

protein-tRNA adaptor activity

The binding activity of a protein that brings together another protein and a tRNA, permitting those molecules to function in a coordinated way.

thymine/thymine mispair binding

Binding to a double-stranded DNA region containing a T/T mispair.

kinetochore adaptor activity

The binding activity of a protein that brings the kinetochore and another molecule into contact, permitting those molecules to function in a coordinated way.

photoreactive repair

The repair of UV-induced T-T, C-T and C-C dimers by directly reversing the damage to restore the original pyrimidines.

aclacinomycin T methylesterase activity

Catalysis of the reaction: aclacinomycin T(1+) + H2O = 15-demethylaclacinomycin T + methanol + H+.

Holliday junction resolvase complex

An endodeoxyribonuclease complex that resolves the 4-way DNA intermediates of a Holliday junction into two separate duplex DNA molecules. Can be branch-migration associated.
