| Abstract | Ribulose bisphosphate carboxylase (RuBisCO) [ 6351728, 12221984] catalyzes the
initial step in Calvin's reductive pentose phosphate cycle in plants as well as purple and green bacteria.
It consists of a large catalytic unit and a small subunit of undetermined function. In plants, the large
subunit is coded by the chloroplastic genome while the small subunit is encoded in the nuclear genome.
Molecular activation of RuBisCO by CO2 involves the formation of a carbamate with the epsilon-amino group
of a conserved lysine residue. This carbamate is stabilized by a magnesium ion. One of the ligands of
the magnesium ion is an aspartic acid residue close to the active site lysine [1969412]. |

The SUPERFAMILY hidden Markov model library has been used to carry
out SCOP domain assignments to all genomes at the superfamily level. Click on the 'Genome Assignments'
icon above to view the genome assignments for this superfamily.
Alignments of sequences to Alignments of sequences to 12 models
in this superfamily are available by clicking on the superfamily level 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequences may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own.
It is possible to browse and view the proteins in the genomes which have
different combinations of domains including a RuBisCo, C-terminal domain domain. Click on the 'Domain Combinations' icon.
To view the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom click on the 'TaxViz' icon above. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.
Undirected domain occurrence networks are available for all superfamilies. Nodes in these networks represent genomes. Connections between nodes represent the presence of domain architectures, which contain the superfamily of interest, in both genomes.
There are 12 hidden Markov models representing the RuBisCo, C-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be viewed by clicking on the icon above.
