Genome structure

The genome for S. pneumoniae is comprised of 2,160,837 base pairs within a single circular chromosome. There are 39.7% GC base pairs in the genome, resulting in 60.3% AT base pairs also present. The genome was figured out by using a random shotgun sequencing technique. They were able to sequence the genome by taking a clinical isolate from the blood of a 30-year-old, male patient. There are 2236 genes that comprise the genome, and of these, 1155 are situated to the right of the replication fork, and 1081 genes are located to the left. There were 1440 predicted proteins that encode for biological roles, 359 that encode for unknown function, and 437 were not able to matched. The genome is also rich in insertion sequences, which comprise of about 5% of the genome.

Cell structure and metabolism

Interesting features of cell structure; how it gains energy; what important molecules it produces.


Ecology

Habitat; symbiosis; contributions to the environment.

Pathology

How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
