lecture 8

Question 1

signal transduction

Answer 1

see two-component regulatory system

Question 2

two-component regulatory system

Answer 2

a regulatory system consisting of two proteins: a sensor kinase and a response regulator

Question 3

sensor kinase protein

Answer 3

one of the members of a two-component regulatory system; a protein that phosphorylates itself in response to an external signal and then transfers the phosphoryl group to a response regulator protein

Question 4

response regulator protein

Answer 4

one of the members of a two-component regulatory system; a protein that is phosphorylated by a sensor kinase and then acts as a regulator, often by binding to DNA

Question 5

quorum sensing

Answer 5

a regulatory system that monitors the population level and controls gene expression based on cell density

Question 6

autoinducer

Answer 6

a small signal molecule that takes part in quorum sensing
