CC   -!- FUNCTION: Chaperone involved, together with gp57, in the assembly of
CC       the distal-half tail fiber of T4 (By similarity). It is necessary for
CC       the maturation of protein gp37 to the dimeric structural subunit P37
CC       (PubMed:8057378). {ECO:0000250|UniProtKB:P03740,
CC       ECO:0000269|PubMed:8057378}.
CC   -!- SIMILARITY: Belongs to the tfa family. {ECO:0000305}.
