Protist in UniProt/NCBI taxonomic tree

Question

[Seq225]

I am trying to do horizontal gene transfer analysis. I want to download the Protist (Protista) sequences from UniProt.

Protists are eukaryotes, and they are a kingdom. Protist is one of the six kingdoms of life. However, I am having some difficulties downloading their sequences from UniProt. I see different Protist taxid in NCBI, such as:

uncultured eukaryotic protist (taxid:1295078) uncultured protist (taxid:1295078) unidentified protist 56059 (taxid:56059) ... ......

Would someone help me to determine how to download the entire set of Protist sequences (the entire Protist kingdom) from UniProt?

Thanks a lot!!

Try - http://protists.ensembl.org/info/website/ftp/index.html

Thanks. The link is very useful. Probably, what I need is here.

Try this link: http://www.phytopathdb.org/pathogens_eg

They have some Protist genomes:

Browse those genomes in the Ensemblr Genomes website(brown link at the bottom of each page after Description)

These ones above are only pathogenic.

I don't think these are protists at all. They are oomycetes.

Phytophthora is morphologically very similar to true fungi yet its evolutionary history is completely distinct. In contrast to fungi, SAR supergroup is more closely related to plants than to animals. Whereas fungal cell walls are made primarily of chitin, Phytophthora cell walls are constructed mostly of cellulose.

Ensembl appears to consider them protists since they have included the sequences in Protist genomes page.

Seq225 : You will need to decide if you like that classification.

[Seq225]

Thanks. I guess the link provided by aditi.qamra has the sequences. However, I am having some trouble downloading files from that server. Hopefully will get it eventually.

Seq225 : Are you using the link I posted above for the genomes page?

[Seq225]

Yes, its actually the same one that aditi posted.

However, what I see in UniProt is that all the taxonomic branches do not contain sequences in a exclusive fashion (probably same applies to Ensembl). I need all metazoan in one file and everything else in a different files. Therefore, some filtering on the downloaded files will probably do the trick.

Thanks for providing the very useful links!!

Thank you very much Natasha.
