Concept explainers
To explain: The sources of cysteine.
Introduction: The bacteria is the unicellular prokaryotic organism that maintains a definite shape since it contains the rigid cell wall. The growth of bacteria requires certain essential nutrients in the medium they grow. Some of the essential nutrients are carbohydrates, proteins and major elements such as carbon, nitrogen, oxygen, sulfur, potassium, magnesium, calcium, phosphorus, potassium etc.
Explanation of Solution
Some of the soil bacteria uses the amino acid cysteine to achieve its normal growth rate. The major source of cysteine is the protein glutathione. The protein glutathione is composed of three amino acids namely cysteine, glutamine and glycine. Most of the soil bacteria involves in the hydrolysis of glutathione that serves as the major source of cysteine. In another case the bacterium itself synthesis cysteine from serine by acetylation reaction thereby it utilizes the sulfur component present in the cysteine for its growth.
