Molecular action of penicillin

Référence de la vidéo 11937574
Molecular action of penicillin. Animation showing the normal growth of a bacterial wall at the molecular level, followed by the same animation with the effect of the antibiotic penicillin shown. The bacterial membrane is across centre, with the bacterial wall (the coating surrounding the membrane) shown above it as a series of interlinked peptidoglycan molecules. These consist of N-acetylglucosamine (G) and N-acetylmuramic acid (M), shown linked to form a mesh here. The animation shows the peptidoglycan monomers being transported across the membrane by the membrane carrier bactoprenol (green) and its phosphate groups (P). The peptidoglycan monomers are inserted into the existing peptidoglycan mesh. The second stage of the animation shows the antibiotic penicillin interfering with the binding step of this construction, preventing further bacterial growth. For this animation without labels, see K004/3281.
