edit headers of a fasta

Question

[Candela]

Hi community, I am not an expert with sed but i want to edit the headers of each sequence in a fasta file. I want to let only the gene id >NODE_39_length_59461_cov_85.505003_1

The header is the following (an entire line):

>NODE_39_length_59461_cov_85.505003_1 # 3 # 2051 # 1 # ID=1_1;partial=10;start_type=Edge;rbs_motif=None;rbs_spacer=None;gc_cont=0.674

Thank you for always helping everybody!
