A PF01541 GIY-YIG GIY-YIG catalytic domain Domain This domain called GIY-YIG is found in the amino terminal region of excinuclease abc subunit c (uvrC), bacteriophage T4 endonucleases segA, segB, segC, segD and segE; it is also found in putative endonucleases encoded by group I introns of fungi and phage. The structure of I-TevI a GIY-YIG endonuclease, reveals a novel alpha/beta-fold with a central three-stranded antiparallel beta-sheet flanked by three helices [4]. The most conserved and putative catalytic residues are located on a shallow, concave surface and include a metal coordination site. PFAM PF01541
