The Redundancy of Peptidoglycan Carboxypeptidases Ensures Robust Cell Shape Maintenance in Escherichia coli [PDF]

open access: yesmBio, 2016
Peptidoglycan (PG) is an essential structural component of the bacterial cell wall and maintains the integrity and shape of the cell by forming a continuous layer around the cytoplasmic membrane.

Modulation of Peptidoglycan Synthesis by Recycled Cell Wall Tetrapeptides

open access: yesCell Reports, 2020
Summary: The bacterial cell wall is made of peptidoglycan (PG), a polymer that is essential for the maintenance of cell shape and survival. During growth, bacteria remodel their PG, releasing fragments that are predominantly re-internalized and recycled.

The new effector AbSCP1 of foliar nematode (Aphelenchoides besseyi) is required for parasitism rice

open access: yesJournal of Integrative Agriculture, 2022
Plant parasitic nematodes secrete effector proteins to parasitize hosts successfully. Of these proteins, serine carboxypeptidases have critical roles in pathogenicity.

The effects of daptomycin on cell wall biosynthesis in Enterococcal faecalis

open access: yesScientific Reports, 2023
Daptomycin is a cyclic lipodepsipeptide antibiotic reserved for the treatment of serious infections by multidrug-resistant Gram-positive pathogens. Its mode of action is considered to be multifaceted, encompassing the targeting and depolarization of ...

[51] Exocellular dd-carboxypeptidases-transpeptidases from Streptomyces [PDF]

open access: yes, 1976
peer reviewedStrains R39 and R61 are soil isolates. Their designations are arbitrary. In strain R39, the cross-link between the peptide units of the wall peptidoglycan extends from the C-terminal D-alanine of one unit to the amino group at the D-center ...

Understanding the constitutive presentation of MHC class I immunopeptidomes in primary tissues

open access: yesiScience, 2022
Summary: Understanding the molecular principles that govern the composition of the MHC-I immunopeptidome across different primary tissues is fundamentally important to predict how T cells respond in different contexts in vivo. Here, we performed a global

Glutamylation of an HIV-1 protein inhibits the immune response by hijacking STING

open access: yesCell Reports, 2023
Summary: Cyclic GMP-AMP synthase (cGAS) recognizes Y-form cDNA of human immunodeficiency virus type 1 (HIV-1) and initiates antiviral immune response through cGAS-stimulator of interferon genes (STING)-TBK1-IRF3-type I interferon (IFN-I) signalingcascade.

BRS1 mediates plant redox regulation and cold responses

open access: yesBMC Plant Biology, 2021
Background Brassinosteroid-insensitive 1 suppressor 1 (BRS1) is a serine carboxypeptidase that mediates brassinosteroid signaling and participates in multiple developmental processes in Arabidopsis. However, little is known about the precise role of BRS1

Selective Cytotoxicity of Carboxypeptidase-activated Methotrexate ex-Peptides

open access: yesPteridines, 1989
Methotrexate ex-pep tides (derivatives in which an amino acid is linked covalently to the ex-carboxyl of the glutamate residue on the parent drug) can be hydrolyzed by specific carboxypeptidases to yield free Methotrexate (MTX) and the corresponding ...
