deposited without that remark, mostly models determined by [[NMR]]. What is unfortunate is that the added REMARK 350 specifies "AUTHOR DETERMINED", although it appears that the authors are not being consulted. An example is [[2z59]], which lacked REMARK 350 until it was added on March 16, 2022 (see the REVDAT records in the PDB format file).

What is unfortunate is that the added REMARK 350 specifies "AUTHOR DETERMINED", although it appears that the authors are not being consulted. An example is [[2z59]] deposited in 2007 and released in 2008, which lacked REMARK 350 until it was added on March 16, 2022 (see the REVDAT records in the PDB format file).


In some cases, more than one putative biological unit is specified in REMARK 350. Biological units specified by the author(s) are distinguished from those predicted by software. An example is [[3fad]], which is explained in [https://pdb101.rcsb.org/learn/guide-to-understanding-pdb-data/biological-assemblies Introduction to Biological Assemblies and the PDB Archive].
