Worms take the 'phyto' out of 'phytochelatins'.
Vatamaniuk OK, Bucher EA, Ward JT, Rea PA. Vatamaniuk OK, et al. Trends Biotechnol. 2002 Feb;20(2):61-4. doi: 10.1016/s0167-7799(01)01873-x. Trends Biotechnol. 2002. PMID: 11814595
Mutagenic definition of a papain-like catalytic triad, sufficiency of the N-terminal domain for single-site core catalytic enzyme acylation, and C-terminal domain for augmentative metal activation of a eukaryotic phytochelatin synthase.
Romanyuk ND, Rigden DJ, Vatamaniuk OK, Lang A, Cahoon RE, Jez JM, Rea PA. Romanyuk ND, et al. Among authors: vatamaniuk ok. Plant Physiol. 2006 Jul;141(3):858-69. doi: 10.1104/pp.106.082131. Epub 2006 May 19. Plant Physiol. 2006. PMID: 16714405 Free PMC article.
