Such diversity in the primary sequence suggests a divergent origin of CopG1 and CopG2.
Agrobacterium tumefaciens and Rhizobium etli did not group with the rest of their family in lineage 6, indicating a divergent origin of SDH in this family.
Interestingly, γ-proteobacteria had at least one member in four of the six lineages described (Lineages 1, 2, 3 and 6), which suggests a divergent origin of the SDH gene among γ-proteobacteria.
They come from wildly divergent origins, but eventually succumb to the same middle-class temptations (Nora leads Nick out of his San Francisco apartment into a single house with a big back yard) and acquire the same grown-up responsibilities.
A stream of research that is particularly developed among organization scholars has argued that collective work is more creative because it can involve individuals from different backgrounds and these divergent origins may inspire the collaborators and push them to make better decisions.
It should be remarked that while the divergent development of neurons and glial cells (including astrocytes) is well studied [ 38, 39], there is little known about the divergent origins of protoplasmic, CD44+ long process, and fibrous astrocytes.
In contrast to the cilia model, which must postulate divergent origins of asymmetry in animals such as mouse, pig, chick, frog, and invertebrates, the intracellular model is compatible with an ancient, highly conserved role for the symmetry-breaking mechanism.
It is paradoxical that while human activities are behind the origin of this divergent lineage, other human activities are contributing to its demise.
In agreement with their divergent evolutionary origin, Pleos-DyP1 and Pleos-DyP4 significantly differed in their kinetic and stability properties.
However, their individual sequence identities with Pleos-DyP4 were always below 40%% (and only 176 191 residues could be aligned) suggesting a divergent evolutionary origin of the latter protein.
After annotating the DyP-encoding genes in the P. ostreatus genome, and analyzing the predicted sequences and molecular structures of the corresponding enzymes, two of them (Pleos-DyP1 and Pleos-DyP4) were selected for heterologous expression and biochemical characterization, due to their divergent evolutionary origin.
