DPST: De Novo Peptide Sequencing with Amino-Acid-Aware Transformers [PDF]
arXiv, 2022 De novo peptide sequencing aims to recover amino acid sequences of a peptide from tandem mass spectrometry (MS) data. Existing approaches for de novo analysis enumerate MS evidence for all amino acid classes during inference. It leads to over-trimming on receptive fields of MS data and restricts MS evidence associated with following undecoded amino ...

Role of amino acid transporters in amino acid sensing [PDF]
The American Journal of Clinical Nutrition, 2014 Amino acid (AA) transporters may act as sensors, as well as carriers, of tissue nutrient supplies. This review considers recent advances in our understanding of the AA-sensing functions of AA transporters in both epithelial and nonepithelial cells.
