    摘要: The present invention relates to enzymes having catalytic activity at a pH below 5.0. The present invention provides hydrolyzing enzymes obtainable from archaeobacteria, in detail to hydrolytic enzymes obtainable from the archaeobacterium Ferroplasma acidiphilum. In general, the present invention provides enzymes which are active and stable at acidic pH values, especially at pH values from 1 to 4, especially in the range of pH 2 to 3, obtainable from Ferroplasma acidiphilum, especially to an esterase, glycosidases and a DNA ligase. In addition to stability and activity at low pH values, the enzymes according to the present invention are all dependent on Fe2+ for their catalytic activity.

    摘要: The invention relates to the growth temperature of organisms, especially plants and microorganisms and the manipulation of the tolerable cultivation temperature. More specifically, the present invention relates to the expression of heterologous proteins in microorganisms, and especially to the heterologous expression of heat sensitive proteins in bacteria, either gram-negative or gram-positive. In a first aspect, the present invention provides a method for manipulation of cells and the resultant cells, wherein at least one gene from a psychrophilic micro organism coding for at least one chaperone or chaperonin is expressed. Such cells are selected among cultivated eukaryotic cells, i.e. animal and plant cells and entire plants, gram-negative and gram-positive bacteria, fungi and yeasts.
