The protein coat that surrounds the infective nucleic acid in some virus particles. It comprises numerous regularly arranged subunits, or capsomeres.

The lipid bilayer of a virion that surrounds the protein capsid. May also contain glycoproteins.

The lipid bilayer of a virion, a complete fully infectious extracellular virus particle.

A spiral cytoskeletal structure located at the apical end of the apical complex in some apicomplexan parasites. Fibers form a left-handed spiral, and are comprised of tubulin protofilaments organized in a ribbon-like structure that differs from the conventional tubular structure characteristic of microtubules.

OBSOLETE. A viral genome composed of deoxyribonucleic acid.

OBSOLETE. A viral genome composed of ribonucleic acid. This results in genome replication and expression of genetic information being inextricably linked.

The plastid organelle found in apicomplexans.

OBSOLETE. A viral genome composed of double stranded RNA.

OBSOLETE. A viral genome composed of single stranded RNA of either positive or negative sense.

OBSOLETE. A single stranded RNA genome with the same nucleotide polarity as mRNA.

Cell division by multiple fission in which nuclei and other organelles in the parent cell divide repeatedly and move to the cell periphery before internal membranes develop around them, producing a large number of daughter cells simultaneously.

The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells.

OBSOLETE. A single stranded RNA genome with the opposite nucleotide polarity as mRNA.

A membrane-bounded organelle found in organisms from the order Kinetoplastida that houses the enzymes of glycolysis.

OBSOLETE. A RNA genome that contains coding regions that are either positive sense or negative sense on the same RNA molecule.

Any process in which a symbiont organism modulates the frequency, rate or extent of erythrocyte aggregation in its host organism, e.g. the binding of parasite-infected erythrocytes to uninfected erythrocytes.

The protein coat that surrounds the infective nucleic acid in some virus particles; the subunits are arranged to form a protein helix with the genetic material contained within. Tobacco mosaic virus has such a capsid structure.

OBSOLETE. Catalysis of the removal of a methyl group from dimethylated lysine at position 4 of the histone H3 protein.

OBSOLETE. Catalysis of the removal of a methyl group from monomethylated lysine at position 4 of the histone H3 protein.
