Crystal structure of E. coli seryl-tRNA synthetase complexed to seryl sulfamoyl adenosine

Structural highlights

6r1m is a 2 chain structure with sequence from Escherichia coli. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

SYS_ECOLI Catalyzes the attachment of serine to tRNA(Ser) (PubMed:7537870). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L-seryl-tRNA(Sec), which will be further converted into selenocysteinyl-tRNA(Sec).^[1] ^[2] ^[3]

Publication Abstract from PubMed

Aminoacyl-tRNA synthetases are ubiquitous and essential enzymes for protein synthesis and also a variety of other metabolic processes, especially in bacterial species. Bacterial aminoacyl-tRNA synthetases represent attractive and validated targets for antimicrobial drug discovery if issues of prokaryotic versus eukaryotic selectivity and antibiotic resistance generation can be addressed. We have determined high-resolution X-ray crystal structures of the Escherichia coli and Staphylococcus aureus seryl-tRNA synthetases in complex with aminoacyl adenylate analogues and applied a structure-based drug discovery approach to explore and identify a series of small molecule inhibitors that selectively inhibit bacterial seryl-tRNA synthetases with greater than 2 orders of magnitude compared to their human homologue, demonstrating a route to the selective chemical inhibition of these bacterial targets.
