Sorry if this seems like a naive and simple question. I have the whole genome of my species as a fasta file and a file containing a list of protein IDs. What is the easiest way to get a file that contains the fasta sequence for each of the proteins in the second file?

What species?
If it is one of the common genomes NCBI is likely to have the protein fasta file available. -
I can get the protein fasta file. It's more the extracting the sequence for my specific list of protein IDs that I'm struggling with.
It is the monarch butterfly so not a particularly common species.Comment

Look into faSomeRecords utility from Jim Kent: http://hgdownload.soe.ucsc.edu/admin.../faSomeRecords I have provided linux link but OS X/Source code is also available at the site.
Provide the list of ID's to faSomeRecords and it will extract the fasta sequence for your ID's, which you can save to a new file.Comment

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...04-22-2024, 07:01 AM -
Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...04-04-2024, 04:25 PM
