Enhanced expression of aconitase raises acetic acid resistance in Acetobacter aceti.

abstract：:Plasmodium falciparum sirtuin, PfSir2, contains histone deacetylase (HDAC) activity that may be central to the regulation of virulence gene expression in the parasites. Although a few reports have been published recently regarding in vitro and in vivo function of PfSir2, expression of the endogenous protein (c. 30 kDa...
