P17313

- VG31_BPT4

UniProt

P17313 - VG31_BPT4

Protein

Capsid assembly protein Gp31

Gene

31

Organism
Enterobacteria phage T4 (Bacteriophage T4)
Status
Reviewed - Annotation score: 2 out of 5- Experimental evidence at protein leveli
  1. 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
