Resistance in VanA-type vancomycin resistant Enterococcus faecium (VREfm) is due to an inducible gene cassette encoding seven proteins ( vanRSHAXYZ ). This provides for an alternative peptidoglycan (PG) biosynthesis pathway whereby d- Alanyl- d- Alan

Ochi (Agric. Biol. Chem. 51:829-835, 1987) has isolated a relaxed mutant of Streptomyces antibioticus, designated relC49, relC49 accumulates significantly lower levels of ppGpp than the parent stain, IMRU3720. At its maximum, the ppGpp level in relC4

We have examined the translational coupling between the first two genes in the S10 ribosomal protein operon. We isolated mutations blocking the translation of the first gene of the operon, coding for S10, and monitored their effects on translation of

Naegleria fowleri is a pathogenic amoeboflagellate that can be evoked to transform from amoebae to flagellates by subculture to nonnutrient buffer. More than half of the amoebae of strains KUL, nN68, and Lovell became enflagellated 300 min after subc

The formation of the components of the cell envelope of Acinetobacter sp. 199A was investigated by measuring the incorporation of [3H]leucine into protein, [14C]galactose into lipopolysaccharide, 32P into phospholipid, and [3H]diaminopimelic acid int

Plasmid pCIS7, containing 11.5 kilobases (kb) of Bacillus subtilis DNA, was isolated from a Tn917 transposon insertion in tetracycline-sensitive B. subtilis KS162. When integrated into the chromosome of B. subtilis 168, this plasmid conferred tetracy

Clostridium pasteurianumexhibits diauxic growth when grown in the presence of both NH3and N2; no nitrogenase activity or formation was detected either serologically or by activity during growth on NH3. During the 60-min lag that ensued after NH3was c

The regulation of the molybdate (MoO42-) transport activity of Clostridium pasteurianum has been studied by observing the effects of NH3, carbamyl phosphate, MoO42-, and chloramphenicol on the ability of cells to take up MoO42-. Compared with cells f

Three thermosensitive deoxyribonucleic acid (DNA) initiation mutants of Escherichia coli exposed to the restrictive temperature for one to two generations were examined for the ability to reinitiate DNA replication after returning to the permissive t

When protein synthesis was blocked in temperature-sensitive deoxyribonucleic acid synthesis mutants of Escherichia coli at nonpermissive temperatures, it reduced the amount of apparent subsequent chain elongation to approximately half that observed i
