The DnaC helicase loader is a dual ATP/ADP switch protein
Abstract Helicases are transferred to replication origins by helicase loading factors. The Escherichia coli DnaC and eukaryotic Cdc6/18 helicase loaders contain ATP sites and are both members of the AAA+ family. One might expect that ATP is required for helicase loading; however, this study on DnaC...

| 520 | |a Abstract Helicases are transferred to replication origins by helicase loading factors. The Escherichia coli DnaC and eukaryotic Cdc6/18 helicase loaders contain ATP sites and are both members of the AAA+ family. One might expect that ATP is required for helicase loading; however, this study on DnaC illustrates that ATP is not actually needed for DnaC to load helicase onto single‐strand DNA (ssDNA). In fact, it seems to be a paradox that after transfer of helicase to DNA, DnaC–ATP inhibits helicase action. In addition, ATP is required for DnaC function at an early step in oriC replication in which ATP stimulates ssDNA binding by DnaC, leading to expansion of the ssDNA bubble at the origin. Two cofactors, ssDNA and DnaB, trigger hydrolysis of ATP, converting DnaC to the ADP form that no longer inhibits DnaB. These observations have led to the idea that DnaC is a ‘dual’ switch protein, where both the ATP and the ADP forms are sequentially required for replication. This dual switching process may underlie the sensitivity of DnaB to even small fluctuations in DnaC levels. | ||

The Escherichia coli DnaC and eukaryotic Cdc6/18 helicase loaders contain ATP sites and are both members of the AAA+ family. One might expect that ATP is required for helicase loading; however, this study on DnaC illustrates that ATP is not actually needed for DnaC to load helicase onto single‐strand DNA (ssDNA). In fact, it seems to be a paradox that after transfer of helicase to DNA, DnaC–ATP inhibits helicase action. In addition, ATP is required for DnaC function at an early step in oriC replication in which ATP stimulates ssDNA binding by DnaC, leading to expansion of the ssDNA bubble at the origin. Two cofactors, ssDNA and DnaB, trigger hydrolysis of ATP, converting DnaC to the ADP form that no longer inhibits DnaB. These observations have led to the idea that DnaC is a ‘dual’ switch protein, where both the ATP and the ADP forms are sequentially required for replication. This dual switching process may underlie the sensitivity of DnaB to even small fluctuations in DnaC levels.

The Escherichia coli DnaC and eukaryotic Cdc6/18 helicase loaders contain ATP sites and are both members of the AAA+ family. One might expect that ATP is required for helicase loading; however, this study on DnaC illustrates that ATP is not actually needed for DnaC to load helicase onto single‐strand DNA (ssDNA). In fact, it seems to be a paradox that after transfer of helicase to DNA, DnaC–ATP inhibits helicase action. In addition, ATP is required for DnaC function at an early step in oriC replication in which ATP stimulates ssDNA binding by DnaC, leading to expansion of the ssDNA bubble at the origin. Two cofactors, ssDNA and DnaB, trigger hydrolysis of ATP, converting DnaC to the ADP form that no longer inhibits DnaB. These observations have led to the idea that DnaC is a ‘dual’ switch protein, where both the ATP and the ADP forms are sequentially required for replication. This dual switching process may underlie the sensitivity of DnaB to even small fluctuations in DnaC levels.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">ATP</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">ADP switch protein</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">DnaB</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">DnaC</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">helicase loader</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fang, Linhua</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">McInerney, Peter</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Georgescu, Roxana E.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">O'Donnell, Mike</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">The EMBO Journal</subfield><subfield code="d">Nature Publishing Group UK, 2023</subfield><subfield code="g">21(2002), 12 vom: 17.

The DnaC helicase loader is a dual ATP/ADP switch protein |
| abstract |
Abstract Helicases are transferred to replication origins by helicase loading factors. The Escherichia coli DnaC and eukaryotic Cdc6/18 helicase loaders contain ATP sites and are both members of the AAA+ family. One might expect that ATP is required for helicase loading; however, this study on DnaC illustrates that ATP is not actually needed for DnaC to load helicase onto single‐strand DNA (ssDNA). In fact, it seems to be a paradox that after transfer of helicase to DNA, DnaC–ATP inhibits helicase action. In addition, ATP is required for DnaC function at an early step in oriC replication in which ATP stimulates ssDNA binding by DnaC, leading to expansion of the ssDNA bubble at the origin. Two cofactors, ssDNA and DnaB, trigger hydrolysis of ATP, converting DnaC to the ADP form that no longer inhibits DnaB. These observations have led to the idea that DnaC is a ‘dual’ switch protein, where both the ATP and the ADP forms are sequentially required for replication. This dual switching process may underlie the sensitivity of DnaB to even small fluctuations in DnaC levels. © European Molecular Biology Organization 2002 |
