Catabolism of tryptophan, anthranilate, and 2,3-dihydroxybenzoate in Trichosporon cutaneum

Properties of anthranilate hydroxylase (deaminating), a flavoprotein from Trichosporon cutaneum.

Anthranilate hydroxylase was purified from the yeast Trichosporon cutaneum. This enzyme is a simple flavoprotein which apparently does not require any additional cofactor for the conversion of anthranilate to 2,3-dihydroxybenzoate. Anthranilate hydroxylase has Mr of approximately 95,000, with subunit Mr of 50,000; it contains 2 mol of FAD/mol of enzyme. A number of compounds in addition to anth...

Uptake of phenol by Trichosporon cutaneum.

The soil yeast Trichosporon cutaneum, which is distinguished by having a strictly oxidative metabolism, can be induced to utilize phenol as a sole carbon source. The present paper shows that such phenol-induced cells contain a specific, energy-dependent uptake system for phenol. Phenol uptake is not directly linked to its o-hydroxylation inside the cell, the first step of phenol metabolism. The...

cis,cis-Muconate cyclase from Trichosporon cutaneum.

The inducible enzyme catalysing the conversion of cis,cis-muconate to (+)-muconolactone was purified 300-fold from the yeast Trichosporon cutaneum, grown on phenol. The enzyme has a sharp pH optimum at pH 6.6. It reacts also with several monohalogen derivatives and with one monomethyl derivative of cis,cis-muconate, but not with cis,trans- or trans,trans-muconate or 3-carboxy-cis,cis-muconate. ...
