Substrate promiscuity of the cyclic dipeptide prenyltransferases from Aspergillus fumigatus ( section sign).

J. Nat. Prod. 72 , 44-52, (2009)

This study reports that a series of tryptophan derivatives with modifications on the side chain or at the indole ring were accepted by two cyclic dipeptide prenyltransferases, CdpNPT and FtmPT1, and c...

Targeting a nuclear anthranilate synthase alpha-subunit gene to the tobacco plastid genome results in enhanced tryptophan biosynthesis. Return of a gene to its pre-endosymbiotic origin.

Plant Physiol. 127(1) , 131-41, (2001)

Anthranilate synthase (AS), the control enzyme of the tryptophan (Trp) biosynthetic pathway, is encoded by nuclear genes, but is transported into the plastids. A tobacco (Nicotiana tabacum) cDNA (ASA2...
