New sub-family of lysozyme-like proteins shows no catalytic activity: crystallographic and biochemical study of STM3605 protein from Salmonella Typhimurium
Phage viruses that infect prokaryotes integrate their genome into the host chromosome; thus, microbial genomes typically contain genetic remnants of both recent and ancient phage infections. Often phage genes ...

Solution NMR and X-ray crystal structures of Pseudomonas syringae Pspto_3016 from protein domain family PF04237 (DUF419) adopt a “double wing” DNA binding motif
The protein Pspto_3016 is a 117-residue member of the protein domain family PF04237 (DUF419), which is to date a functionally uncharacterized family of proteins. In this report, we describe the structure of Ps...

Open AccessAnalysis of nucleoside-binding proteins by ligand-specific elution from dye resin: application to Mycobacterium tuberculosis aldehyde dehydrogenases
We show that Cibacron Blue F3GA dye resin chromatography can be used to identify ligands that specifically interact with proteins from Mycobacterium tuberculosis, and that the identification of these ligands can ...

Structure of an acetyl-CoA binding protein from Staphylococcus aureus representing a novel subfamily of GCN5-related N-acetyltransferase-like proteins
We have determined the solution NMR structure of SACOL2532, a putative GCN5-like N-acetyltransferase (GNAT) from Staphylococcus aureus. SACOL2532 was shown to bind both CoA and acetyl-CoA, and structures with and...
