The first structure of (S)-3-O-geranylgeranylglyceryl phosphate synthase (GGGPS) from a thermoacidophilic archaeon, Thermoplasma acidophilum, with the substrate sn-glycerol 1-phosphate is described. Structural comparisons of this enzyme with other structurally determined archaeal GGGPS proteins are described.
PDB reference: (S)-3-O-geranylgeranylglyceryl phosphate synthase, 6jo3
The crystal structure of an iron superoxide dismutase from Acanthamoeba castellanii, a pathogenic amoeba, was determined at 2.33 Å resolution. It belonged to space group P61, with 12 molecules forming three tetramers in the asymmetric unit.
PDB reference: AcFeSOD, 6j55
Phylogenetic and structural characterization of the only predicted leucine-rich repeat-containing protein from the human pathogen Treponema pallidum is reported.
PDB reference: leucine-rich repeat protein (TpLRR), 6mlx
Co-crystal structure of the Fusobacterium ulcerans ZTP riboswitch using an X-ray free-electron laser
An X-ray free-electron laser was used to determine the structure of the ZTP riboswitch, an RNA motif that is responsible for regulating gene expression in bacteria.
PDB reference: Fusobacterium ulcerans ZTP riboswitch, 6od9
The crystal structure of PssZ has been determined at 1.6 Å resolution. PssZ belongs to glycoside hydrolase family 8 and adopts a classical (α/α)6-barrel fold.
PDB reference: PssZ from Listeria monocytogenes, 6r2m
p-Hydroxybenzoate hydroxylase (PobA) is a possible drug target to combat tetracycline resistance. Here, the 2.2 Å resolution structure of PobA from the pathogen Pseudomonas putida complexed with FAD is reported and is compared with those of PobA from P. aeruginosa and P. fluorescens.
PDB reference: p-hydroxybenzoate hydroxylase, complex with FAD, 6dll
The crystal structure of protein kinase CK2a1 in complex with 5-iodotubercidin, an ATP-analogue inhibitor, was determined at 1.78 Å resolution. This structure should facilitate the discovery of selective CK2a1 inhibitors.
PDB reference: CK2a1, complex with 5-iodotubercidin, 6jwa
This study reports the three-dimensional structure of the substrate binding of a methionine transporter from Streptococcus pneumoniae bound to methionine. The high-resolution structure provides atomic-level details of its substrate specificity.
