Phage_holin_6_1 or Holin_LLH identifies a family of phage holins from a number of phage and prophage regions of Gram-positive bacteria. Like other holins, it is large for holins (about 100-160 amino acids) with stretches of hydrophobic sequence and is encoded adjacent to lytic enzymes. Holin LLH family is found in phage of Firmicutes and have an N-terminal transmembrane segment.
