The replication origin of plasmid P1 contains an array of five repeats (iterons) that bind the plasmid-encoded initiator RepA. Within the array lies the repA promoter, which becomes largely repressed
In the primary visual cortex, neurons with similar response preferences are grouped into domains forming continuous maps of stimulus orientation and direction of movement. These properties are widely
Amino acid sequence comparison suggests that the structure of Escherichia coli methionine aminopeptidase (EC 3.4.11.18) and the C-terminal domain of Pseudomonas putida creatinase (EC 3.5.3.3) are rela
Chloroperoxidase is a versatile heme enzyme which can cross over the catalytic boundaries of other oxidative hemoproteins and perform multiple functions. Chloroperoxidase, in addition to catalyzing cl
We describe the molecular characterization of two mutations responsible for galactosemia, an inherited disorder of galatose metabolism that causes jaundice, cataracts, and mental retardation in humans
