Structure of the RNA-processing inhibitor RraA from Thermus thermophilis
Overview
The menG gene product, thought to catalyze the final methylation in, vitamin K(2) synthesis, has recently been shown to inhibit RNase E in, Eschericha coli. The structure of the protein, since renamed RraA, has, been solved to 2.3 A using the multiple-wavelength anomalous diffraction, method and selenomethionine-substituted protein from Thermus thermophilus., The six molecules in the asymmetric unit are arranged as two similar, trimers which have a degree of interaction, suggesting biological, significance. The fold does not support the postulated methylation, function. Genomic analysis, specifically a lack of an RNase E homologue in, cases where homologues to RraA exist, indicates that the function is still, obscure.
