Embryonic factor 1 (FAC1) is one of the earliest expressed plant genes and, encodes an AMP deaminase (AMPD), which is also an identified herbicide, target. This report identifies an N-terminal transmembrane domain in, Arabidopsis FAC1, explores subcellular fractionation, and presents a 3.3-A, globular catalytic domain x-ray crystal structure with a bound, herbicide-based transition state inhibitor that provides the first glimpse, of a complete AMPD active site. FAC1 contains an (alpha/beta)(8)-barrel, characterized by loops in place of strands 5 and 6 that places it in a, small subset of the amidohydrolase superfamily with imperfect folds., Unlike tetrameric animal orthologs, FAC1 is a dimer and each subunit, contains an exposed Walker A motif that may be involved in the dramatic, combined K(m) (25-80-fold lower) and V(max) (5-6-fold higher) activation, by ATP. Normal mode analysis predicts a hinge motion that flattens basic, surfaces on each monomer that flank the dimer interface, which suggests a, reversible association between the FAC1 globular catalytic domain and, intracellular membranes, with N-terminal transmembrane and disordered, linker regions serving as the anchor and attachment to the globular, catalytic domain, respectively.
