APD prediction and calculation: mol weight: 5898.083; Mol formula: C279H451N69O67S1. Sequence alignment revealed its similarity (49%) to Aureocin A53 (AP1131). leaderless. Chemical modification: The N-terminal methionine of lacticin Q is formylated. Bacteriocins that lack leader or signal sequences are expected to have N-formylmethionine at their N termini
