Beschreibung:
Oligomerization of a peptide was attempted in a flow reactor that simulated a submarine hydrothermal system. When fluid containing glycine repeatedly circulated through the hot and cold regions in the reactor, oligopeptides were made from glycine. When divalent ions (such as copper ions) were added under acidic conditions, oligoglycine was elongated up to hexaglycine. This observation suggests that prebiotic monomers could have oligomerized in the vicinity of submarine hydrothermal vents on primitive Earth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Imai, E -- Honda, H -- Hatori, K -- Brack, A -- Matsuno, K -- New York, N.Y. -- Science. 1999 Feb 5;283(5403):831-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of BioEngineering, Nagaoka University of Technology, Nagaoka 940-2188, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9933163" target="_blank"〉PubMed〈/a〉
