Linearizability conditions for 1:-5 Lotka-Volterra two-dimensional complex quartic systems
In this paper we investigate the linearizability problem for the planar Lotka-Volterra complex quartic systems which are 1:-5 linear systems perturbed by homogeneous polynomials of degree 4, that is to say, we consider systems of the form ẋ = x(1 ...

Cofactor Fingerprinting with STD NMR to Characterize Proteins of Unknown Function: Identification of a Rare cCMP Cofactor Preference [PDF]
Proteomics efforts have created a need for better strategies to functionally categorize newly discovered proteins. To this end, we have employed saturation transfer difference NMR with pools of closely related cofactors, to determine cofactor preferences.

The Bacterial Photosynthetic Reaction Center as a Model for Membrane Proteins [PDF]
Membrane proteins participate in many fundamental cellular processes. Until recently, an understanding of the function and properties of membrane proteins was hampered by an absence of structural information at the atomic level.

APOBEC-1 cofactors regulate APOBEC3-induced mutations in hepatitis B virus
APOBEC3 proteins (A3s) play an important role in host innate immunity against viruses and DNA mutations in cancer. A3s-induced mutations in both viral and human DNA genomes vary significantly from non-lethal mutations in viruses to localized ...

Archaeal heme a synthase: evolutionary trajectory distinct from bacterial homologs
Hemes are iron-containing porphyrin compounds that play a crucial role in a wide array of biological processes. Heme a synthase (HAS) is a crucial enzyme that facilitates the biosynthesis of heme a, an essential heme variant that serves as a cofactor in ...

Nucleocapsid Structure of Negative Strand RNA Virus
Negative strand RNA viruses (NSVs) include many important human pathogens, such as influenza virus, Ebola virus, and rabies virus. One of the unique characteristics that NSVs share is the assembly of the nucleocapsid and its role in viral RNA synthesis ...

The transition element molybdenum needs to be complexed by a special cofactor to gain catalytic activity. Molybdenum is bound to a unique pterin, thus forming the molybdenum cofactor (Moco), which, in different variants, is the active compound at the catalytic site of all molybdenum-containing enzymes in nature, except bacterial molybdenum nitrogenase.
