Identification of peptidases in Nicotiana tabacum leaf intercellular fluid

open access: yesProteomics, 2008
Peptidases in the extracellular space might affect the integrity of recombinant proteins expressed in, and secreted from, plant cells. To identify extracellular peptidases, we recovered the leaf intercellular fluid from Nicotiana tabacum plants by an ...

Equine peptidases: Correspondence with human peptidases and polymorphism for erythrocyte peptidase a

Biochemical Genetics, 1979
Equine erythrocyte peptidases were compared to the six human erythrocyte peptidases, A, B, C, D, E, and F, regarding substrate specificity, relative activity, and electrophoretic mobility. Five equine erythrocyte peptidases appeared homologous to human peptidases A, B, D, E, and F.

‘Species’ of peptidases

bchm, 2007
Abstract A good system for the naming and classification of peptidases can contribute much to the study of these enzymes. Having already described the building of families and clans in the MEROPS system, we here focus on the lowest level in the hierarchy, in which the huge number of individual peptidase proteins are assigned to a lesser ...

Peptidase in the cornea

Experimental Eye Research, 1969
Peptidase activity, operative at neutral pH, was found in bovine cornea and conjunctiva with a synthetic substrate assay. The same peptidase was found previously in commercial bacterial collagenase preparations. Cell fractionation of homogenates revealed the activity to be maximal in the high-speed supernatant of the corneal and conjunctival epithelium,

Tripeptidyl-peptidase II: A multi-purpose peptidase

The International Journal of Biochemistry & Cell Biology, 2005
Tripeptidyl-peptidase II is a high-molecular weight peptidase with a widespread distribution in eukaryotic cells. The enzyme sequentially removes tripeptides from a free N-terminus of longer peptides and also displays a low endopeptidase activity. A role for tripeptidyl-peptidase II in the formation of peptides for antigen presentation has recently ...

Chorionic peptidase inactivates GnRH as a post‐proline peptidase

International Journal of Gynecology & Obstetrics, 1992
Recently, we have described a chorionic peptidase (C-ase-1) which inactivates gonadotropin releasing hormone (GnRH), oxytocin, angiotensin II and thyrotropin releasing hormone. Since all these hormones contain a proline residue, we proposed that C-ase-1 may act as a post-proline peptidase.

Leader peptidase

Molecular Microbiology, 1991
SummaryThe Escherichia coli leader peptidase has been vital for unravelling problems in membrane assembly and protein export. The role of this essential peptidase is to remove amino‐terminal leader peptides from exported proteins after they have crossed the plasma membrane.
