Thermus thermophilus polyploid cells directly imaged by X-ray laser diffraction
This study demonstrates that XFELs offer a novel approach for visualizing the internal nanostructures of living, micrometer-sized, polyploid bacterial cells.PMID:37302826 | DOI:10.2323/jgam.2023.06.002 (Source: Journal of General and Applied Microbiology)

Synergistic effect of secondary metabolites isolated from Pestalotiopsis sp. FKR0115 in overcoming β-lactam resistance in MRSA
J Gen Appl Microbiol. 2023 Jun 10. doi: 10.2323/jgam.2023.06.001. Online ahead of print.ABSTRACTSix aromatic secondary metabolites, pestalone (1), emodin (2), phomopsilactone (3), pestalachlorides B (4), C (5), and D (6), were isolated from Pestalotiopsis sp. FKR-0115, a filamentous fungus collected from white moulds growing on dead branches in Minami Daito Island. The efficacy of these secondary metabolites against methicillin-resistant Staphylococcus aureus (MRSA) with and without meropenem (β-lactam antibiotic) was evaluated using the paper disc method and broth microdilution method. The chemical structures of the isol...

Convergent evolution of nitrogen-adding enzymes in the purine nucleotide biosynthetic pathway, based on structural analysis of adenylosuccinate synthetase (PurA)
J Gen Appl Microbiol. 2023 Jun 10. doi: 10.2323/jgam.2023.05.002. Online ahead of print.ABSTRACTAdenylosuccinate synthetase (PurA) is an enzyme responsible for the nitrogen addition to inosine monophosphate (IMP) by aspartate in the purine nucleotide biosynthetic pathway. And after which the fumarate is removed by adenylosuccinate lyase (PurB), leaving an amino group. There are two other enzymes that catalyze aspartate addition reactions similar to PurA, one in the purine nucleotide biosynthetic pathway (SAICAR synthetase, PurC) and the other in the arginine biosynthetic pathway (argininosuccinate sythetase, ArgG). To inve...
