>cd00007 35EXOc 3'-5' exonuclease. The 35EXOc domain is responsible for the 3'-5' exonuclease proofreading activity of prokaryotic DNA polymerase I (pol I) and other enzymes, it catalyses the hydrolysis of unpaired or mismatched nucleotides. This domain consists of the amino-terminal half of the Klenow fragment in E. coli pol I. 35EXOc is also found in the Werner syndrome helicase (WRN), focus forming activity 1 protein (FFA-1) and ribonuclease D (RNase D).
