A	PF18667	Baseplate upper protein immunoglobulin like domain (BppU_IgG)	Baseplate upper protein immunoglobulin like domain	This is a beta-sandwich immunoglobulin fold domain, which resembles the plexin-A2 C-terminal domain in structure. In baseplate upper protein (BppU, also known as ORF48) trimer, this domain plays part in surrounding the Dit hexameric core [1].	Domain
B	PF21470	Minor structural protein 5-like, C-terminal domain (BppU-like_C)	Minor structural protein 5-like, C-terminal domain	This domain is found at the C-terminal end of Minor structural protein 5 from Lactococcus phage Tuc2009 (BppU) and similar proteins from tailed bacteriophages and prophages found mostly in firmicutes. BppU is a viral baseplate component. This domain ...	This domain is found at the C-terminal end of Minor structural protein 5 from Lactococcus phage Tuc2009 (BppU) and similar proteins from tailed bacteriophages and prophages found mostly in firmicutes. BppU is a viral baseplate component. This domain folds into a structure formed mostly by beta-strands [1].	Domain
C [auth G]	PF21454	Major structural protein 1, jelly-roll domain (MSP1_barrel)	Major structural protein 1, jelly-roll domain	This entry represents a beta barrel domain found towards the N-terminal of phage Tuc2009 receptor binding protein (RBP) which forms the head domain, involved in carbohydrate recognition [1].
