text_B: The CidA / LrgA Holin -LRB- CidA / LrgA Holin -RRB- Family -LRB- TC # 1 .. E. 14 -RRB- is a group of proteins named after CidA -LRB- TC # 1 .. E. 14.1.2 -RRB- and LrgA -LRB- TC # 1 .. E. 14.1.1 -RRB- of Staphylococcus aureus .. Staphylococcus aureus. Staphylococcus aureus. CidA and LrgA are homologous holin and anti-holin proteins , each with 4 putative transmembrane segments -LRB- TMSs -RRB- .. Members of the CidA / LrgA holin family also include putative murine hydrolase exporters from a wide range of Gram-positive and Gram-negative bacteria as well as archaea .. Gram-positive. Gram-positive bacteria. Gram-negative bacteria. Gram-negative bacteria. archaea. archaea. Most CidA / LrgA holin family proteins vary in size between 100 and 160 amino acyl residues -LRB- aas -RRB- in length although a few are larger .
