Research on Xanthurenic Acid.

VII. On the “Xanthurenicase”

Abstract

1) We studied on the decomposition of xanthurenic acid by enzyme action, and named this enzyme the “xanthurenicase”.
2) In this connection, the results obtained from the examinations by both paper-partition-chromatography and absorption spectrum lead us to presume that the substance thus formed by the decomposition of xanthurenic acid may be a derivate of phenol caused by the splitting of a pyridin ring of xanthurenic acid.
