Substrate specificity of prostate-specific antigen (PSA)

open access: yesChemistry & Biology, 1998
The serine protease prostate-specific antigen (PSA) is a useful clinical marker for prostatic malignancy. PSA is a member of the kallikrein subgroup of the (chymo)trypsin serine protease family, but differs from the prototypical member of this subgroup, tissue kallikrein, in possessing a specificity more similar to that of chymotrypsin than trypsin. We

The Substrate Specificity of Pantethinase [PDF]

open access: yesEuropean Journal of Biochemistry, 1973
The substrate specificty of pantethinase, the mammalian enzyme which has been isolated from horse kidney cortex, has been studied. The real substrate has been found to be pantetheine in the reduced form, and the involvement of one or more—SH groups of the enzyme is also considered.A number of other compounds, chemically related to pantetheine, has also

Inflammatory caspase substrate specificities

open access: yesmBio
ABSTRACT Caspases are a family of cysteine proteases that act as molecular scissors to cleave substrates and regulate biological processes such as programmed cell death and inflammation. Extensive efforts have been made to identify caspase substrates and to determine factors that dictate substrate specificity ...

Comparative study of manufacturing techniques for coronagraphic binary pupil masks: masks on substrates and free-standing masks

open access: yes, 2012
We present a comparative study of the manufacture of binary pupil masks for coronagraphic observations of exoplanets. A checkerboard mask design, a type of binary pupil mask design, was adopted, and identical patterns of the same size were used for all ...
