The new beta-D-glucosidase in terpenoid-isoquinoline alkaloid biosynthesis in Psychotria ipecacuanha. [PDF]
J Biol Chem, 2008 Ipecac alkaloids produced in the medicinal plant Psychotria ipecacuanha such as emetine and cephaeline possess a monoterpenoid-tetrahydroisoquinoline skeleton, which is formed by condensation of dopamine and secologanin. Deglucosylation of one of the condensed products N-deacetylisoipecoside (1 alpha(S)-epimer) is considered to be a part of the ...

Cyclotide discovery in Gentianales revisited--identification and characterization of cyclic cystine-knot peptides and their phylogenetic distribution in Rubiaceae plants. [PDF]
Biopolymers, 2013 ABSTRACT Cyclotides are a unique class of ribosomally synthesized cysteine‐rich miniproteins characterized by a head‐to‐tail cyclized backbone and three conserved disulfide‐bonds in a knotted arrangement. Originally they were discovered in the coffee‐family plant Oldenlandia affinis (Rubiaceae) and have since been identified in several species of the ...
