The chloroplast-encoded large subunit ribosomal RNA gene of several free-living green algae contains group I introns at Escherichia coli genic positions 1917, 1931, 1951, and 2449. Herein we report the presence of group I introns at these p...
Effect of oxidative stress on the growth of magnetic particles in Magnetospirillum magneticum [0.03%]
氧化应激对磁小体细菌磁小体生长的影响
Radu Popa,Wen Fang,Kenneth H Nealson et al.
Radu Popa et al.
Individual magnetosome-containing magnetic mineral particles (MMP) from magnetotactic bacteria grow rapidly such that only a small fraction (5%) of all magnetosomes contain dwarf (< or =20 nm) MMP. Studies of the developmental stages in the...
Repression of the acid ZrfA/ZrfB zinc-uptake system of Aspergillus fumigatus mediated by PacC under neutral, zinc-limiting conditions [0.03%]
白僵菌PacC介导的弱酸条件下低锌水平下ZrfA/ZrfB锌吸收系统的抑制作用
Jorge Amich,Fernando Leal,José A Calera
Jorge Amich
The ZrfA and ZrfB transporters are components of a zinc-uptake system of Aspergillus fumigatus that mainly operates under acidic, zinc-limiting conditions. Expression of the genes zrfA and zrfB is up-regulated by the transcriptional activat...
Identification of a cell-wall channel in the corynemycolic acid-free Gram-positive bacterium Corynebacterium amycolatum [0.03%]
无结冷球酸类脂的棒状分枝杆菌细胞壁通道的鉴定
Ursula Dörner,Betina Schiffler,Marie Antoinette Lanéelle et al.
Ursula Dörner et al.
As part of a comparative study of the cell wall of corynebacteria, a channel-forming protein was characterized in Corynebacterium amycolatum, a species devoid of corynemycolic acids. Corynebacterium amycolatum cells were disrupted and the c...
