摘要
Malaria caused by the mosquito-transmitted parasite Plasmodium is the cause of enormous number of deaths every year in the tropical and subtropical areas of the world. Among four species of Plasmodium, Plasmodium falciparum causes most fatal form of malaria. With time, the parasite has developed insecticide and drug resistance. Newer strategies and advent of novel drug targets are required so as to combat the deadly form of malaria. Helicases is one such class of enzymes which has previously been suggested as potential antiviral and anticancer targets. These enzymes play an essential role in nearly all the nucleic acid metabolic processes, catalyzing the transient opening of the duplex nucleic acids in an NTP-dependent manner. DNA helicases, from the PcrA/UvrD/Rcp subfamily are important for the survival of the various organisms. Members from this subfamily can be targeted and inhibited by a variety of synthetic compounds. UvrD from this subfamily is the only member present in the P. falciparum genome, which shows no homology with UvrD from human and thus can be considered as a strong potential drug target. In this manuscript we provide an overview of UvrD family of helicases and bioinformatics analysis of UvrD from P. falciparum.
