Comparative Analysis of Barophily-Related Amino Acid Content in Protein Domains of Pyrococcus abyssi and Pyrococcus furiosus

Figure 2

Evolutionary accumulation of protein domain structures defined at FSF level of the structural hierarchy in SCOP. The cumulative plot divides FSFs into those that are shared between Pyrococcus and those that are species-specific. Domain age is provided in a relative scale (𝑛𝑑, node distance) or in timescales in billions of years (Gy) according to a molecular clock of FSFs. The Venn diagram describes the actual FSF counts in the proteomes of P. furiosus and P. abyssi.
