The MotA and MotB proteins are thought to comprise elements of the stator component of the flagellar motor of Escherichia coli. In an effort to understand interactions among proteins within the motor, we attempted to identify extragenic suppressors of 31 dominant, plasmid-borne alleles of motA. Strains containing these mutations were either nonmotile or had severely impaired motility. Four of t...

Bacterial flagellar motors rotate, obtaining power from the membrane gradient of protons or, in some species, sodium ions. Torque generation in the flagellar motor must involve interactions between components of the rotor and components of the stator. Sites of interaction between the rotor and stator have not been identified. Mutational studies of the rotor protein FliG and the stator protein M...

The commercial BD ProbeTec ET (BDPT) system for the detection of Neisseria gonorrhoeae and Chlamydia trachomatis from clinical specimens was compared with our in-house LightCycler real-time PCR (LC-PCR) assays. Specimens initially positive by the BDPT system were retested by our LC-PCR assays. Our results for C. trachomatis testing indicate a 91.2% agreement when the results of 114 clinical spe...

Entrevista com Ana Elizabete Mota.

Over the past 15 years, the Australian tourism accommodation sector has seen a significant shift from motels and caravan parks to units in multi-owner tourism accommodation premises, i.e. serviced apartments and holiday flats. It is estimated that by the end of 2006, the number of guest nights in serviced apartment complexes will have exceeded those for motels and, in some destinations, even th...

Flagella act as semirigid helical propellers that are powered by reversible rotary motors. Two membrane proteins, MotA and MotB, function as a complex that acts as the stator and generates the torque that drives rotation. The genome sequence of Pseudomonas aeruginosa PAO1 contains dual sets of motA and motB genes, PA1460-PA1461 (motAB) and PA4954-PA4953 (motCD), as well as another gene, motY (P...

Buscamos compreender, por meio da análise textual de dois diários mulheres pretas e faveladas, Quarto despejo (1960), Carolina Maria Jesus, Diário do fim mundo (2020), Nilda Carvalho Mota, as representações sobre ações policiais na periferia São Paulo. Analisamos o contexto sociopolítico, diário como suporte memórias verdades gênero literário. Para Jesus a polícia garantiu sua sobrevivência, ma...
