| pubmed-article:2635869 | pubmed:abstractText | (ADP-ribose)n glycohydrolase activity was inhibited in vitro by lignin, a naturally occurring polymethoxyphenolic compound. However, coniferyl alcohol, which is a main component of lignin, was not inhibitory even at 100 micrograms/ml. Lignin caused competitive inhibition with respect to the substrate (ADP-ribose)n and its Ki value was 18 micrograms/ml. These results suggest that lignin with a polymerized structure has a functional domain that interacts with the (ADP-ribose)n glycohydrolase molecule at the same site as (ADP-ribose)n. | lld:pubmed |
