Enzymic method of detecting analytes and novel substrates therefor |
摘要 |
A small enzymically inactive peptide fragment of an enzyme (e.g. ribonuclease S-peptide) is used as the label and conjugated with the complementary fragment (S-protein) to form an enzyme which catalyzes a primary reaction whose product is, or leads to, an essential coenzyme or prosthetic group for a second enzyme which catalyzes a secondary reaction leading to a detectable result indicating the presence of analyte. Also disclosed are novel synthetic substrates for the primary reaction. Substrates for ribonuclease S conjugate enzyme are of the formula R-X where R is a pyrimidine 3'-phosphate moiety and X is a leaving group linked to R through the 3'-phosphate group and leads to said coenzyme or prosthetic group, e.g. via riboflavin, thiamine, pyridoxal, pyridoxine or pyridoxine phosphate.
