Cauliflower mosaic virus (CaMV) coat protein precursor (pre-CP) has 489 amino acids (p57) and is processed by the viral proteinase into three major forms: p44. p39. and p37. The N- and C-terminal extensions of pre-CP are released during maturation by the virus-encoded proteinase. https://mandisattictoyers.shop/product-category/train-sets/
