An overview of 25years of research on Thermococcus kodakarensis, a genetically versatile model organism for archaeal research.

Abstract

Almost 25years have passed since the discovery of a planktonic, heterotrophic, hyperthermophilic archaeon named Thermococcus kodakarensis KOD1, previously known as Pyrococcus sp. KOD1, by Imanaka and coworkers. T. kodakarensis is one of the most studied archaeon in terms of metabolic pathways, available genomic resources, established genetic engineering techniques, reporter constructs, in vitro transcription/translation machinery, and gene expression/gene knockout systems. In addition to all these, ease of growth using various carbon sources makes it a facile archaeal model organism. Here, in this review, an attempt is made to reflect what we have learnt from this hyperthermophilic archaeon.
