Protein Family Models

This family consists of bacterial MreB and Mbl proteins as well as two related archaeal sequences. MreB is known to be a rod shape-determining protein in bacteria and goes to make up the bacterial cytoskeleton. Genes coding for MreB/Mbl are only found in elongated bacteria, not in coccoid forms. It has been speculated that constituents of the eukaryotic cytoskeleton (tubulin, actin) may have evolved from prokaryotic precursor proteins closely related to today's bacterial proteins FtsZ and MreB/Mbl [1].

Hsp70 chaperones help to fold many proteins. Hsp70 assisted folding involves repeated cycles of substrate binding and release. Hsp70 activity is ATP dependent. Hsp70 proteins are made up of two regions: the amino terminus is the ATPase domain and the carboxyl terminus is the substrate binding region. [1]. 9476895. The Hsp70 and Hsp60 chaperone machines..

Hsp70 (heat shock protein 70) family protein is a molecular chaperone involved in DNA replication, protein folding and the stress response; similar to Grapevine leafroll-associated virus movement protein Hsp70h, which transports viral genomes to neighboring plant cells directly through the plasmodesmata
