Figure 8From: Site-specific and synergistic stimulation of methylation on the bacterial chemotaxis receptor Tsr by serine and CheWThe influences of serine and CheW on methylation. The enlarged representation of the methylation region from one Tsr subunit in panel A illustrates the locations relative to the N and C-termini of Tsr (N and C), and the cytoplasmic domain hairpin (at bottom). For simplicity, all other representations depict (panels B to D) show only the two methylation helices. Numbers next to the four sites are relative rates (r); not in parentheses are rates relative to the rate without ligand (r = v+ligand(s)/vno ligand). The r-values in parentheses are the rates at various sites (v n ) relative to the rate at site four (v4) under the same conditions (r = v n /v4). A: no ligand;B: 500 μM serine; C: 60 μM CheW; D: both serine and CheW.Back to article page
