1. PII proteins as global regulators of bacterial nitrogen metabolism
Sammanfattning : Nitrogen is an essential element to sustain life, being a component of most biological macromolecules. In spite of the abundance of gaseous N2, the availability of nitrogen compounds that can be readily used by most microorganisms is scarce and its production energetically demanding. LÄS MER
2. Metabolic regulation of nitrogen fixation in Rhodospirillum rubrum
Sammanfattning : Nitrogen, along with carbon, hydrogen and oxygen, is amongst the most abundant elements in all living cells. The capability to convert atmospheric dinitrogen to biologically usable nitrogen compounds is only found in some prokaryotes. LÄS MER
3. Regulation of Glutamine Synthetase in the Diazotroph Rhodospirillum rubrum
Sammanfattning : The bacterial cell needs ammonia for synthesis of glutamine from glutamate. Only one enzyme is able to catalyze this reaction, namely glutamine synthetase (GS). GS can be regulated both transcriptionally and post-translationally and it is present in all kingdoms of life. LÄS MER
4. Extracellular serine proteases as virulence factors in nematophagous fungi: Molecular characterization and functional analysis of the PII protease in Arthrobotrys oligospora
Sammanfattning : Nematophagous fungi are parasites of nematodes, thus they have been considered and tested for biological control of parasitic nematodes, but so far with limited success. Due to the fact that the nematode cuticle is composed of proteins it is likely that fungal extracellular proteases are involved in the infection of nematodes. LÄS MER
