How to remove a part of the header from a FASTA file?

Here is an example of the header from the FASTA file

>PSR83604 cdna supercontig:Red5_PS1_1.69.0:ps1sf1427:11608:20559:-1 gene:CEY00_Acc33586 gene_biotype:protein_coding transcript_biotype:protein_coding description:Cysteine-rich receptor-like protein kinase

I want to keep just the 'description' part which contains the protein name and remove rest of them from the header.

I tried using 'sed', but I'm going wrong somewhere.

Can someone help?

Thank you in advance..

This question is so often asked. Try searching Biostars externally using google (trim fasta headers site: biostars.org) and you will find plenty of example threads. Here is one.

Thank you very much. I already tried some of the solutions mentioned in Biostars. But still it didn't work. That's why I decided to post up a separate question. I'll look into it more.

Is never a good description of the problem. You need to be specific as to what did not work.
