From lignins to tannins: forty years of enzyme studies on the biosynthesis of phenolic compounds
Gross G
Phytochemistry . 2007 Jun; 69(18):3018-31. PMID: 17559893
In the early 1960s, enzyme studies increasingly began to replace the common 'feeding' experiments in which labeled tracers were applied to living plants or plant parts for elucidating metabolic pathways....

Enzymology of gallotannin and ellagitannin biosynthesis
Niemetz R, Gross G
Phytochemistry . 2005 Sep; 66(17):2001-11. PMID: 16153405
Gallotannins and ellagitannins, the two subclasses of hydrolyzable tannins, are derivatives of 1,2,3,4,6-penta-O-galloyl-beta-D-glucopyranose. Enzyme studies with extracts from oak leaves (Quercus robur, syn. Quercus pedunculata; Quercus rubra) and from staghorn...

Ellagitannin biosynthesis: laccase-catalyzed dimerization of tellimagrandin II to cornusiin E in Tellima grandiflora
Niemetz R, Gross G
Phytochemistry . 2003 Nov; 64(7):1197-201. PMID: 14599517
An enzyme has been purified from leaves of the weed Tellima grandiflora (fringe cups, Saxifragaceae) that catalyzed the O2-dependent oxidation of the monomeric ellagitannin, tellimagrandin II, to a dimeric derivative,...

Biosynthesis of the dimeric ellagitannin, cornusiin E, in Tellima grandiflora
Niemetz R, Schilling G, Gross G
Phytochemistry . 2003 Aug; 64(1):109-114. PMID: 12946409
First evidence for the in vitro synthesis of a dimeric ellagitannin has been obtained with cell-free extracts from the weed Tellima grandiflora (fringe cups, Saxifragaceae). Partially purified enzyme preparations from...

Oxidation of pentagalloylglucose to the ellagitannin, tellimagrandin II, by a phenol oxidase from Tellima grandiflora leaves
Niemetz R, Gross G
Phytochemistry . 2003 Mar; 62(3):301-6. PMID: 12620341
A new enzyme has been isolated from leaves of the weed Tellima grandiflora (fringe cups, Saxifragaceae) that catalyzed the O(2)-dependent oxidation of 1,2,3,4,6-penta-O-galloyl-beta-D-glucopyranose to tellimagrandin II, the first intermediate in...

Gallotannin biosynthesis: two new galloyltransferases from Rhus typhina leaves preferentially acylating hexa- and heptagalloylglucoses
Frohlich B, Niemetz R, Gross G
Planta . 2002 Nov; 216(1):168-72. PMID: 12430027
Current enzyme studies on the biosynthesis of gallotannins with cell-free extracts from leaves of staghorn sumac (Rhus typhina L.) revealed the existence of two new beta-glucogallin-dependent galloyltransferases (EC 2.3.1.-) that...
