malfunction
deregulatory effects of transcription factor MYB8 silencing on AT1 control, altered metabolite profile, overview. Silencing of acyltransferase AT1 impairs polyamine accumulation
metabolism
the enzyme AT1 is involved in a branch of jasmonic acid signaling that defends Nicotiana attenuata plants against herbivores: jasmonic acid, via key transcription factor MYB8's transcriptional control of AT1 and DH29 genes, controls the entire branch of polyamine biosynthesis, overview. AT1, DH29, and CV86 contribute to distinct, but interconnected, MYB8-controlled hydroxycinnamoylputrescine and hydroxycinnamoylspermidine pools
physiological function
the enzyme is responsible for caffeoylputrescine biosynthesis in tobacco
