What types of acc. no. exist?

Hello community,

I would like to have an overview of all formats a acc. no. can have/ types of acc. no.. So far I have been working with acc. no. with 3 letters + 5 numerals or 3 l. + 7 n. or 3 l. + 9 n. (eg. MAM88718, MBA1146895 or WP_088983797).

But now I have encountered some with only 1 numeral +3 letters (eg. 5YFE). It looks like a pdb ID to me rather than an acc. no. but I got that reference from a search in the non-redundant NCBI DB...

So...

I would like to know where they come from.

Does anyone know what kind of acc. no. this is?

And...

I remember some time ago I found a nice list that displayed an overview of all kinds of acc. no. like:

  • Nucleotide: 1 letter + 5 numerals OR 2 letters + 6 numerals

  • Protein: 3 letters + 5 numerals

  • WGS: 4 letters + 2 numerals for WGS assembly version + 6-8 numerals

  • MGA: 5 letters + 7 numerals

... just like here: https://letgen.org/GGGB%20Genetics%20&%20Bioinformatics/accession-number/ or here: https://academic.oup.com/nar/article/44/D1/D733/2502674 (but neither of those is the website I remember - it was nicer).

This is a good summary of all GenBank accession numbers. UniProt accession numbers are described at this link. 5YFE is a PDB ID. These databases cross-reference data where possible to facilitate linking information together.
