DNA repair protein rhp54; Involved in DNA repair. May have a role in the processing of replication structures during late replication that is different from its role in the repair of radiation damage; Belongs to the SNF2/RAD54 helicase family.

DNA repair protein rhp55; Required for radiation resistance and meiotic viability and acts in recombination and recombinational DNA repair pathways.

DNA repair and recombination protein rad22; Active in the repair of DNA damage and in mating-type switching. Probably involved in the repair of DNA double-strands breaks. Has a role in promoting S phase completion; Belongs to the RAD52 family.

Meiotic recombination protein dmc1; Required for meiotic recombination and cell cycle progression. Binds to single and double-stranded DNA, in the presence of magnesium, and exhibits DNA-dependent ATPase activity. Promotes DNA strand annealing and strand exchange via DNA recombinase activity and forms helical and stacked ring nucleoprotein filaments. Belongs to the RecA family. DMC1 subfamily.

ATP-dependent DNA helicase srs2; ATP-dependent DNA helicase involved in DNA repair at least for UV-induced lesions. Also aids the recombinational repair of camptothecin-induced collapsed replication forks. Belongs to the helicase family. UvrD subfamily.

DNA repair protein rhp57; Involved in recombination DNA repair and in the repair of gamma-ray-induced damage.

Crossover junction endonuclease mus81; Interacts with eme1 to form a DNA structure-specific endonuclease with substrate preference for branched DNA structures with a 5'-end at the branch nick. Typical substrates include 3'-flap structures, D-loops, replication forks and nicked Holliday junctions. May be required in mitosis for the processing of stalled or collapsed replication fork intermediates. May be required in meiosis for the repair of meiosis-specific double strand breaks subsequent to single- end invasion (SEI). Belongs to the XPF family.

Exodeoxyribonuclease 1; 5'->3' double-stranded DNA exonuclease that could act in a pathway that corrects mismatched base pairs.

DNA topoisomerase 3; Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)- enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand than undergoes passage around the unbroken strand thus removing DNA supercoils. Fina [...]
