| 摘要 |
A novel class of pectin methyl esterases, having pectin methyl esterase activity not inhibited by tyrosine selective inhibitors, is disclosed. The enzymes are present in certain plant enzyme extracts, particularly papain, ficin, bromelain and wheat germ lipase. The enzymes are effective to reduce the degree of methoxylation of pectin without significant reduction in pectin molecular weight. |
