Conserved motifs of MutL proteins
PublicationtThe MutL protein is best known for its function in DNA mismatch repair (MMR). However, there isevidence to suggest that MutL is not only the linker connecting the functions of MutS and MutH in MMR,but that it also participates in other repair systems, such as Very Short Patch (VSP), Base Excision (BER)and Nucleotide Excision Repair (NER). This study set out to identify the most highly conserved aminoacid sequence motifs in MutL...

MutL protein as a constituent of vsp, ner and mmr repair systems
PublicationMutS and MutL proteins are renowned mostly for their functions in well-characterized, post-DNA replication mis- match repair system (MMR). However, there is growing evidence that MMR system is not the only field of action for these pro- teins. Moreover, the participation in MMR does not even have to be their primary function. There are some reports indicat- ing involvement of MutL in BER, NER and VSP (very short patch repair)....

MUTL PROTEIN AS A COMMON CONSTITUENT OF VSP, BER, NER AND MMR REPAIR SYSTEMS

Białka prokariotycznego systemu MMR: rola oraz interakcje
PublicationUszkodzenia komórkowego DNA w postaci błędnie sparowanych lub niesparowanych zasad azotowych są wynikiem niewłaściwie zachodzących procesów metabolizmu DNA, takich jak replikacja, rekombinacja oraz naprawa DNA. Utrwalenie tego rodzaju zmian prowadzi do powstania mutacji. System MMR (ang. DNA mismatch repair) usuwa te uszkodzenia przyczyniając się do zwiększenia wierności replikacji DNA oraz utrzymania stabilności genomu komórki....

Conservation and diversity of MutS proteins
PublicationThe homologues of MutS, mismatch repair protein, exist in all prokaryotes, with the exception of Actinobacteria, Mollicutes and part of the Archaea. Multiple alignments of 316 MutS amino acid sequences from 169 species revealed conserved residues and sequence motifs distinguishing MutS homologues. All MutS homologues show high conservation within the ATPase domain. MutS1, the homologue responsible for DNA mismatch recognition,...

MutS3: a MutS homologue of unknown biological function
PublicationThe homologues of MutS proteins are widespread among both Prokaryotes and Eukaryotes. MutS designated as MutS1 is a part of MMR (mismatch repair) system which is responsible for removal of mispaired bases and small insertion/deletion loops in DNA. Initially, the only MutS homologues known were those engaged in mismatch repair and these were later designated as MutS1. Subsequently, the MutS2 homologue was distinguished. MutS2 does...

The construction of bifunctional fusion proteins consisting of MutS and GFP
PublicationSkonstruowano białka chimeryczne zawierające białko MutS z Thermus thermophilus i białko zielonej fluoresceiny GFP z Aequorea victoria, posiadające dla łatwiejszego oczyszczania domeny oligo-histydynowe na N- lub C-końcu. Fuzyjne białka rozpoznawały niekomplementarności w DNA podobnie do MutS T. thermophilus. Fluorescencyjne białka rozpoznające niekomplementarne DNA mogą być użyteczne w wykrywaniu jednonukleotydowych polimorfizmów...
