PHENYLALANYL-TRNA SYNTHETASE FROM THERMUS THERMOPHILUSPHENYLALANYL-TRNA SYNTHETASE FROM THERMUS THERMOPHILUS
Structural highlights
Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe crystal structure of phenylalanyl-tRNA synthetase from Thermus thermophilus, solved at 2.9 A resolution, displays (alpha beta)2 subunit organization. Unexpectedly, both the catalytic alpha- and the non-catalytic beta-subunits comprise the characteristic fold of the class II active-site domains. The alpha beta heterodimer contains most of the building blocks so far identified in the class II synthetases. The presence of an RNA-binding domain, similar to that of the U1A spliceosomal protein, in the beta-subunit is indicative of structural relationships among different families of RNA-binding proteins. The structure suggests a plausible catalytic mechanism which explains why the primary site of tRNA aminoacylation is different from that of the other class II enzymes.
