Figure 2From: Site-specific and synergistic stimulation of methylation on the bacterial chemotaxis receptor Tsr by serine and CheWInitial rates of methylation at the four major sites in Tsr. A: The extent of methylation (moles of methyl groups per mole CheR) was determined using inner membranes samples as described in Methods. Symbols: EQQQ, △; QEQQ, ▷; QQEQ, ▽; QQQE, ◁ B: The initial rates of methylation for each of the single site forms.Back to article page
