reflecting changes in the CCD

[keitaroyam]

Following #40, inconsistencies from the CCD was checked.

Now, following entries are obsolete:

2VO 39E E7U F3O LL8 M60 ON8 PSD QHD RTV SOC T0Q YYQ

Following entries have been updated, because atomic compositions or bonding patterns were changed.

5Z8 8BA 9NG BP5 CLZ CV6 DG9 DLC ETA N8K O18 PFX Q75 Q78 QFW RHJ T0N X1J YOA

Note 8BA has wrong chemistry (both P-OP1 and P-OP2 were double bond) which was fixed manually.

There are some changes in following entries as well, but they couldn't be updated because of metals or borons.

1CL 39B FSO K3G OEX OEY PTT RAX RUX TPT

Needs testing before merging.

[GaribMurshudov]

Did you report 8BA and others where there are chemistry changes to the PDB.
mtals will come soon. borons will have to wait.

[keitaroyam]

Not yet, will do. done

Updated DG9-SER link

LINK: RES-NAME-1 DG9 ATOM-NAME-1 P2A RES-NAME-2 SER ATOM-NAME-2 OG DELETE ATOM O4 1

NOTE: T0N should be fixed; this acedrg seems to have a problem with atom name having two single quotations.

[keitaroyam]

T0N fixed (by a newer acedrg). still needs tests

[drlemmus]

T0N is only in one NMR model so I cannot test in pdb-redo.

[keitaroyam]

N8K is used in 6tg4 and 7pox. 6tg4 is good, but 7pox uses different atom names. I initially thought atom names have not been updated in 7pox, but they are also inconsistent with alt_atom_id (so updating in gemmi didn't help at all).

Similarly, X1J is inconsistent with both PDB entries (5sns and 5s65). Again alt_atom_id didn't help, which is (partly) incorrect.

[drlemmus]

I'll report those to the PDB annotators

[keitaroyam]

@drlemmus any update from the PDB?

[drlemmus]

Not yet, I'm afraid.

[keitaroyam]

7CQ in the CCD was fixed and that in our library was updated accordingly.

[GaribMurshudov]

It looks reasonable to me

[keitaroyam]

In the CCD, now 8NK BJ3 BQG HEK are obsolete, and 6VO and X1J were updated. The X1J issue (inconsistent atom names in the pdb models) has been sorted.

[keitaroyam]

As discussed in #48, single-atom entries ZCM RHF CF BS3 TA0 AM 4TI 0BE have been added.

By the way, should we remove RH RH3 BI TA BE from the library? In the CCD, they don't exist, and RHF BS3 TA0 0BE exist instead.

[keitaroyam]

Redundant and CCD-nonexistent single atom entries RH RH3 BI TA BE ER have been removed

[GaribMurshudov]

Do we have replacements for these single atom monomers?

[keitaroyam]

Yes. They were Rh, Rh, Bi, Ta, Be, Er, respectively. Here is the summary of single-atom entries:
