General annotation (Comments)

Function	Cleaves the spore coat proteins spoIVA and safA. May cooperate with tgl to mediate the temperature-dependent cross-linking of coat proteins like gerQ. Ref.3 Ref.5
Subcellular location	Forespore outer membrane. Note: Synthesized in the mother cell compartment and assembled on the surface of the forespore. Ref.4
Developmental stage	Expressed in the mother cell compartment from T4 of sporulation.
Induction	Induced by sigK.
Disruption phenotype	According to Ref.4, cells have an altered coat protein composition; cotT, yeeK, yxeE, cotF, safA and spoIVA proteins are present at increased levels and/or exist as precursors. According to Ref.5, cells show no effects on vegetative growth or spore resistance to heat, chloroform or lysozyme. The germination of yabG mutant spores in L-alanine and in a mixture of L-asparagine, D-glucose, D-fructose and potassium chloride was the same as that of the wild-type spores. Heat treatment for 20 minutes at 60 degrees Celsius, which maximally activates the tgl enzymatic activity, causes cross-linking of gerQ in isolated yabG-deleted spores but not in tgl/yabG double-mutant spores. Additionally, the germination frequency of the tgl/yabG double-mutant spores in the presence of L-alanine with or without heat activation at 60 degrees Celsius is lower than that of wild-type spores (). Ref.5 Ref.4
Sequence similarities	Belongs to the peptidase U57 family.
