18(6):655-67.
PMID: 23771821
The multiheme cytochromes from Thioalkalivibrio nitratireducens (TvNiR) and Escherichia coli (EcNrfA) reduce nitrite to ammonium. Both enzymes contain His/His-ligated hemes to deliver electrons to their active sites, where a Lys-ligated...

11(7):1249-55.
PMID: 21331413
Counting the different subpopulations of cells in a fingerprick of human blood is important for a number of clinical point-of-care (PoC) applications. It is a challenge to demonstrate the integration...
