Peptide Ligands of AmiA, AliA, and AliB Proteins Determine Pneumococcal Phenotype [PDF]
Frontiers in Microbiology, 2018 The Ami-AliA/AliB oligopeptide permease of Streptococcus pneumoniae has been suggested to play a role in environmental sensing and colonisation of the nasopharynx by this human bacterial pathogen by binding peptides derived from bacterial neighbours of ...

In vivo proteomics identifies the competence regulon and AliB oligopeptide transporter as pathogenic factors in pneumococcal meningitis [PDF]
PLoS Pathogens, 2019 Streptococcus pneumoniae (pneumococci) is a leading cause of severe bacterial meningitis in many countries worldwide. To characterize the repertoire of fitness and virulence factors predominantly expressed during meningitis we performed niche-specific ...

Streptococcus pneumoniae Proteins AmiA, AliA, and AliB Bind Peptides Found in Ribosomal Proteins of Other Bacterial Species [PDF]
Frontiers in Microbiology, 2018 The nasopharynx is frequently colonized by both commensal and pathogenic bacteria including Streptococcus pneumoniae (pneumococcus). Pneumococcus is an important pathogen responsible for bacterial meningitis and community acquired pneumonia but is also ...

Peptide Occurring in Enterobacteriaceae Triggers Streptococcus pneumoniae Cell Death [PDF]
Frontiers in Cellular and Infection Microbiology, 2019 Non-encapsulated Streptococcus pneumoniae often possess two genes, aliB-like ORF 1 and aliB-like ORF 2, in place of capsule genes. AliB-like ORF 1 is thought to encode a substrate binding protein of an ABC transporter which binds peptide SETTFGRDFN ...

AmiA and AliA peptide ligands are secreted by Klebsiella pneumoniae and inhibit growth of Streptococcus pneumoniae [PDF]
Scientific Reports, 2022 Streptococcus pneumoniae colonizes the human nasopharynx, a multi-species microbial niche. Pneumococcal Ami-AliA/AliB oligopeptide permease is an ABC transporter involved in environmental sensing with peptides AKTIKITQTR, FNEMQPIVDRQ, and AIQSEKARKHN ...

Diminished Pneumococcal-Specific CD4+ T-Cell Response is Associated With Increased Regulatory T Cells at Older Age [PDF]
Frontiers in Aging, 2021 Respiratory infection caused by Streptococcus pneumoniae is a leading cause of morbidity and mortality in older adults. Acquired CD4+ T cell mechanism are essential for the protection against colonization and subsequent development of infections by S ...

Foreign peptide triggers boost in pneumococcal metabolism and growth [PDF]
BMC Microbiology, 2018 Background Nonencapsulated Streptococcus pneumoniae bacteria are successful colonizers of the human nasopharynx and often possess genes aliB-like ORF 1 and 2 in place of capsule genes.

Uncovering the prevalence, key biogenesis enzymes, and biological significance of archaeal lipoproteins [PDF]
Nature CommunicationsLipid-anchored proteins are integral components of cell surfaces. In bacteria, lipidation of proteins with a conserved lipobox motif ([L/V/I]−3 [A/S/T/V/I]−2 [G/A/S]−1 [C]+1) is catalyzed by prolipoprotein diacylglyceryl transferase (Lgt).
