    DNA methylation is mediated by DNA methyltransferases Bi-directional synthesis In many prokaryotes two replication forks develop from at the initiation site, each initiation fork traveling in opposite directions as shown here. Thus, what strand is lagging or leading depends on which replication fork you are

    The parasitophorous vacuole (PV) membrane The parasitophorous vacuole (PV) membrane (PVM) (blue) undergoes distinct morphological phases during parasite egress. On completion of schizogony, the merozoites align around the central food vacuole (dark brown) and the parasitophorous vacuole rounds up

    PLCd1 PH domain; pleckstrin homology (PH) domains of PLCd1 from the plasma membranes Infection of human erythrocytes by the apicomplexan malaria parasite Plasmodium falciparum results in endovacuolar uptake of 4 host proteins that reside in erythrocyte detergent-resistant membranes (DRMs). Whether this vacuolar transport reflects selecti

    Model of lipid and protein uptake into the erythrocyte DIV and the malarial vacuole (A) The erythrocyte membrane contains a variety of phospholipids (PS, PI/PIP2, PE, PG, etc) and raft (stomatin, flotillins) and nonraft (actin, spectrin) proteins, most of which are taken up into DIV membranes. However, PE- and PG-type phospholipids are s

    Vacuolar secretion pathways Vacuolar secretion pathways in Plasmodium. Effectors and virulence factors follow the general SRP/Sec61-dependent (Signal Recognition Particle/Sec61 translocon) parasitic secretion pathway starting in the endoplasmic reticulum (ER) and progressing through
