Prokaryotic Viruses and Metabolism Overview

Prokaryotic Viruses

• Pleomorphic family of prokaryotic viruses is identified as Plasma viridae.
• The structure of archaeal viruses resembles that of existing bacteriophages, particularly found in Methanobacterium and Halo bacterium.

Virus Families and Hosts

• Judiviridae family of viruses primarily uses insects as hosts.
• Various virus families identified include Mycoviridae, noted for their different host preferences.

Unique Viruses

• A unique lineage described is the Nobel Strand DNA virus, found in the amoeba named Poly Phage.
• Other notable viruses include Hepatitis, Pox virus, Baculovirus, and Mimivirus.

Carrier Molecules in Metabolism

• Acetyl CoA functions as the carrier molecule for acetyl in fatty acid biosynthesis, particularly in the Melonine pathway.
• Other potential carrier molecules like ATP and Acyl carrier protein are not the primary carriers in this context.
