We have isolated and characterized a cDNA, PfAT208, encoding hydroxycinnamoyl-CoA: anthocyanin 3-O-glucoside-6"-O-acyltransferase (3AT) from Perilla frutescens. The identity of the cDNA was established by determination of the reaction products with recombinant enzyme overexpressed in Escherichia coli. The deduced amino acid sequence has a few regions that are conserved in a CoA-dependent acyltransferase family. The recombinant enzyme produced in yeast could utilize cyanidin 3-glucoside and cyanidin 3,5-diglucoside, putative substrates in vivo, as well as other anthocyanins. The inhibitory effects of diethyl pyrocarbonate and N-ethylmaleimide on the recombinant 3AT activities suggest that histidine and cysteine residues are important for their catalytic function. These properties are in common with anthocyanin 5-O-glucoside-6"-O-acyltransferase (5AT). In Northern analysis, a transcript of PfAT208 was detected in the young leaves of perilla red forma. The properties of other cDNAs, gentian GAT106 and petunia PhAT48, isolated during the above cloning procedure are also described. << Less

Identification and characterization of a novel anthocyanin malonyltransferase from scarlet sage (Salvia splendens) flowers: an enzyme that is phylogenetically separated from other anthocyanin acyltransferases.

Anthocyanin acyltransferases (AATs) catalyze a regiospecific acyl transfer from acyl-CoA to the glycosyl moiety of anthocyanins, thus playing an important role in flower coloration. The known AATs are subfamily members of an acyltransferase family, the BAHD family, which play important roles in secondary metabolism in plants. Here, we describe the purification, characterization, and cDNA cloning of a novel anthocyanin malonyltransferase from scarlet sage (Salvia splendens) flowers. The purified enzyme (hereafter referred to as Ss5MaT2) is a monomeric 46-kDa protein that catalyzes the transfer of the malonyl group from malonyl-CoA to the 4"'-hydroxyl group of the 5-glucosyl moiety of anthocyanins. Thus, it is a malonyl-CoA:anthocyanin 5-glucoside 4"'-O-malonyltransferase. On the basis of the partial amino acid sequences of the purified enzyme, we isolated a cDNA that encodes an acyltransferase protein. The steady-state transcript level of the gene was the highest in recently opened, fully pigmented flowers and was also correlated with the trend observed for an AAT gene responsible for the first malonylation step during salvianin biosynthesis. Immunoprecipitation studies using antibodies against the recombinant acyltransferase protein corroborated the identity of this cDNA as that encoding Ss5MaT2. The deduced amino acid sequence of Ss5MaT2 showed a low similarity (22-24% identity) to those of AATs and lacked the AAT-specific signature sequence. A phylogenetic analysis suggested that Ss5MaT2 is more related to acetyl-CoA:benzylalcohol acetyltransferase (BEAT) rather than to AAT. This is another example in which enzymes with similar, although not identical, substrate evolved from different branches of the BAHD family. << Less
