Penicillin V

**Semantic type:** Antibiotic|Organic Chemical|Pharmacologic Substance

**Definition:** A member of the penicillin family exhibiting broad-spectrum antibiotic property. Penicillin V binds to penicillin binding proteins (PBP), the enzymes that catalyze the synthesis of peptidoglycan, which is a critical component of the bacterial cell wall. This leads to the interruption of cell wall synthesis, consequently leading to bacterial cell growth inhibition and cell lysis.
