 Research Interest and recent work
The laboratory of Structural Biology at NIPGR is interested in understanding various DNA repair and recombination mechanisms in plants from structural and biochemical perspectives. Recently we have identified At-HIGLE, a GIY-YIG endonuclease to be a possible plant Slx1 with resolve Holliday Junction (four-way DNA molecules) resolving potential.
