(2009-05-15)The regulatory mechanisms that govern heterocyst development in Anabaena sp. strain PCC 7120 have been continuously refined over the last two decades. In this work, we show that three of the sigma factor genes present in ...
-
(2011-10-21)Tyrosine hydroxylase (TyrH) is the first and rate-limiting enzyme of catecholamine synthetic pathway, and its regulation is critical for controlling catecholamine synthesis. The well recognized regulatory mechanisms are ...

(Texas A&M University, 2004-09-30)Time-optimal solutions provide us with the fastest means to regulate a system in presence of input constraints. This advantage of time-optimal control solutions is offset by the fact that their real-time implementation ...
-
Antibiotic resistance emerged shortly after the introduction of antibiotics into the field of medicine, bringing about a challenging concern. Resistance to antibiotics is encoded by antibiotic resistance genes, among other ...

(2006-08-16)Coxiella burnetii is a gram negative, obligate intracellular bacterium. It is the etiologic agent of Q fever in a variety of species including livestock, humans and arthropods. The bacterium infects the monocytes of its ...
-
(2021-04-22)The circadian clock is a conserved endogenous time keeping mechanism that controls up to half of the eukaryotic genome at the level of transcript abundance. In addition to clock control of transcript abundance, our lab ...

Studies of the relationship of protein structure to regulation and catalysis in tyrosine hydroxylase (Texas A&M University, 2007-09-17)Tyrosine hydroxylase (TyrH) catalyzes the rate-limiting step in the synthesis of the catecholamine neurotransmitters dopamine, epinephrine, and norepinephrine. Phosphorylation of Ser40 of rat TyrH activates the enzyme by ...
