Protein
Capsid assembly protein Gp31
Gene
31
Organism
Enterobacteria phage T4 (Bacteriophage T4)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

Essential for proper capsid assembly. In absence of Gp31 the major capsid protein (Gp23) assembles into 'lumps'. Acts as a co-chaperonin with the host groEL protein.1 Publication
