Claim by claim

What the story asserts. With no source study, there is nothing to check these against.

Claim 1 of 6Not checkedA joint research group led by Ryo Tanifuji and Hiroki Oguri from the University of Tokyo and Yoshikazu Tanaka from Tohoku University successfully visualized SacC, an enzyme that plays a key role in building the complex five-ring core of safracin B.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 2 of 6Not checkedThe core structure made by SacC is shared with trabectedin, a drug used to treat soft tissue sarcoma.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 3 of 6Not checkedThe enzyme carries out a seven-step catalytic cascade, stitching together two new carbon-to-carbon bonds and producing a five-ring core scaffold in a single pass.View evidenceHide evidence

As statedseven-step catalytic cascade

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 4 of 6Not checkedThe researchers designed small molecules that mimicked enzyme intermediates and found that a partner protein called SacE dramatically improved the enzyme's behavior in solution.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 5 of 6Not checkedUsing cryo-electron microscopy at Tohoku University, they reconstructed a three-dimensional model at near-atomic resolution and captured an early stage of the enzyme cycle.View evidenceHide evidence

As statednear-atomic level

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 6 of 6Not checkedThe article says the method could have broad applicability to related enzymes and may help optimize existing compounds or create new ones.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.
