Simple-Two Component Signaling in Bacteria

Question 1

Receptor Features

Answer 1

1) Kinase activity 2) Response Regulator (regulates gene expression) 3) Typically histidine kinase

Question 2

Simple-Two Component Signaling Process

Answer 2

1) Cell produces chemical 2) Chemical binds to histidine kinase 3) histidine kinase phosphorylates response element 4) response element regulates gene expression
