Analysis of sisomicin binding sites in Micromonospora inyoensis cell wall
Sisomicin binding sites are located in the cell wall. They are the carboxyl groups of peptidoglycans, which are major components of the cell wall. The carboxyl groups have negative charges which can bind the positively charged amino groups of sisomicin. When the negative charges of the carboxyl grou...

Summary: | Sisomicin binding sites are located in the cell wall. They are the carboxyl groups of peptidoglycans, which are major components of the cell wall. The carboxyl groups have negative charges which can bind the positively charged amino groups of sisomicin. When the negative charges of the carboxyl groups of the peptidoglycans are changed to neutral or positive charges, sisomicin does not bind to the cell wall. Magnesium ions bind to the cell wall in competition with sisomicin, and have a weak affinity for the cell wall binding sites compared with sisomicin. The binding molar ratio of sisomicin to magnesium ions was approximately 1 to 10. |
