A mutation in Escherichia coli K-12 results in a requirement for thiamine and a decrease in L-serine deaminase activity.
Mutants of Escherichia coli K-12 deficient in L-serine deaminase (L-SD) activity have been isolated. These strains required thiamine and grew normally when it was provided. The decrease in L-SD activity caused no obvious metabolic deficiency. A study of revertants and transductants showed that a sin...
