Is helicase an enzyme
WebDNA helicases catalyze the disruption of the hydrogen bonds that hold the two strands of double-stranded DNA together. This energy-requiring unwinding reaction results in the formation of the single-stranded DNA required as a template or reaction intermediate in DNA replication, repair and recombination. WebHelicases are enzymes, that unwind double-stranded DNA-DNA, RNA-DNA, or RNA-RNA polynucleotides in an adenosine triphosphate (ATP)–dependent reaction. The function of the helicase of flaviviruses is assumed to be the unwinding of the plus RNA and minus RNA strands of the genome during the viral replication cycle.

WebThe relative inhibitory potential of the tested compounds from Amphimedon was explored against HCV NS3 protease and helicase enzymes using an in silico approach via molecular docking. The docking study showed that most of the identified compounds were able to interact with the active sites of both HCV NS3 protease and helicase domains, ... WebBoth the RecD and RecB subunits are helicases, i.e., energy-dependent molecular motors that unwind DNA (or RNA in the case of other proteins).The RecB subunit in addition has a nuclease function. Finally, RecBCD enzyme (perhaps the RecC subunit) recognizes a specific sequence in DNA, 5'-GCTGGTGG-3', known as Chi (sometimes designated with the Greek …
WebHelicase is the first replication enzyme to load on at the origin of replication ^3 3. Helicase's job is to move the replication forks forward by "unwinding" the DNA (breaking the hydrogen bonds between the nitrogenous base pairs). WebAn enzyme called helicase then separates the DNA strands by breaking the hydrogen bonds between the nitrogenous base pairs. Recall that AT sequences have fewer hydrogen …
