SYSTEMATIC NAME
IUBMB Comments
N-(5-phospho-beta-D-ribosyl)anthranilate aldose-ketose-isomerase
In some organisms, this enzyme is part of a multifunctional protein, together with one or more other components of the system for the biosynthesis of tryptophan [EC 2.4.2.18 (anthranilate phosphoribosyltransferase), EC 4.1.1.48 (indole-3-glycerol-phosphate synthase), EC 4.1.3.27 (anthranilate synthase) and EC 4.2.1.20 (tryptophan synthase)].

insertion of the cleavage sequence of human cytomegalovirus, HCMV, protease, which is an attractive target for antiviral drug development because of its essential function in viral replication, the enzyme serves as substrate for the protease in the screening assay for small molecule inhibitors of the protease, coexpression of HCMV protease with the engineered Trp1p substrate in yeast cells results in site-specific cleavage and functional inactivation of the Trp1p enzyme, thereby leading to an arrest of cell proliferation, this growth arrest can be suppressed by the addition of validated HCMV protease inhibitors, overview

COMMENTARY
LITERATURE
biotechnology
-
the work provides a method of exchanging variably sized loops within the (beta/alpha)8 fold, affording a novel starting point for the screening of novel activities as well as modest diversions from an original activity
