A novel ACE inhibitory peptide from Pelodiscus sinensis Wiegmann meat water-soluble protein hydrolysate

open access: yesAmino Acids
Pelodiscus sinensis meat is a nutritional food and tonic with angiotensin-converting enzyme (ACE) inhibitory activities. To identify the bioactive substances responsible, several bioinformatics methods were integrated to enable a virtual screening for ...

Understanding conserved amino acids in proteins [PDF]

open access: yesarXiv, 2000
It has been conjectured that evolution exerted pressure to preserve amino acids bearing thermodynamic, kinetic, and functional roles. In this letter we show that the physical requirement to maintain protein stability gives rise to a sequence conservatism pattern that is in remarkable agreement with that found in natural proteins.

Application of nitrogen metabolism in autotrophic bacteria to chemosynthetic bioregeneration in space missions, supplement [PDF]

open access: yes
The chemolithotroph, Hydrogenomonas eutropha, was considered as a life support, bioregenerative system. This project focuses on several metabolic functions that are related to the proposed nitrogen cycle between man and this microbe.

The d-amino acid oxidase of Neurospora [PDF]

open access: yes, 1944
Among artificially produced mutants of the mold Neurospora have been found strains lacking the ability to synthesize specific amino acids (1, 2). In the course of biochemical and genetic studies of this group of mutants it was observed that some of the ...

Thermal proteome profiling and proteome analysis using high‐definition mass spectrometry demonstrate modulation of cholesterol biosynthesis by next‐generation galeterone analog VNPP433‐3β in castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
Elevated level of cholesterol is positively correlated to prostate cancer development and disease severity. Cholesterol‐lowering drugs, such as statins, are demonstrated to inhibit prostate cancer. VNPP433‐3β interrupts multiple signaling and metabolic pathways, including cholesterol biosynthesis, AR‐mediated transcription of several oncogenes, mRNA 5′

d-Amino acids differentially trigger an inflammatory environment in vitro

open access: yesAmino Acids
Studies in vivo have demonstrated that the accumulation of d-amino acids (d-AAs) is associated with age-related diseases and increased immune activation. However, the underlying mechanism(s) of these observations are not well defined. The metabolism of d-

Amino acid substitution matrices for protein conformation identification [PDF]

open access: yesarXiv, 2004
Methods for alignment of protein sequences typically measure similarity by using substitution matrix with scores for all possible exchanges of one amino acid with another. Although widely used, the matrices derived from homologous sequence segments, such as Dayhoff's PAM matrices and Henikoff's BLOSUM matrices, are not specific for protein conformation

Germline variants in CDKN2A wild‐type melanoma prone families

open access: yesMolecular Oncology, EarlyView.
Among melanoma‐prone families, wild‐type for CDKN2A and CDK4, some have pathogenic variants in genes not usually linked to melanoma. Furthermore, rare XP‐related variants and variants in MC1R are enriched in such families. Germline pathogenic variants in CDKN2A are well established as an underlying cause of familial malignant melanoma. While pathogenic

Creatine homeostasis and the kidney: comparison between kidney transplant recipients and healthy controls

open access: yesAmino Acids
Creatine is a natural nitrogenous organic acid that is integral to energy metabolism and crucial for proper cell functioning. The kidneys are involved in the first step of creatine production. With kidney transplantation being the gold-standard treatment
