Three phases in the evolution of the standard genetic code: how translation could get started [PDF]

, 2007
A primordial genetic code is proposed, having only four codons assigned, GGC meaning glycine, GAC meaning aspartate/glutamate, GCC meaning alanine-like and GUC meaning valine-like.

A mutant of Neurospora crassa deficient in cytochrome c heme lyase activity cannot import cytochrome c into mitochondria [PDF]

, 1988
The nuclear cyt-2-1 mutant of Neurospora crassa is characterized by a gross deficiency of cytochrome c (Bertrand, H., and Collins, R. A. (1978) Mol. Gen. Genet. 166, 1-13).

Insights Into the Antigenic Repertoire of Unclassified Synaptic Antibodies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We sought to characterize the sixth most common finding in our neuroimmunological laboratory practice (tissue assay‐observed unclassified neural antibodies [UNAs]), combining protein microarray and phage immunoprecipitation sequencing (PhIP‐Seq). Methods Patient specimens (258; 133 serums; 125 CSF) meeting UNA criteria were profiled;

Effects of Interaction of Leucine and Valine on Growth, Body Wall Amino Acids Composition, and Digestive Ability of Sea Cucumber Apostichopus japonicus

Progress in Fishery Sciences
Branched chain amino acids (BCAAs) are neutral amino acids containing branched aliphatic chains on the α-carbon, including leucine (Leu), isoleucine, and valine (Val), accounting for 18%–20% of the total amino acids in animal and plant proteins.

Frailty Exacerbates Disability in Progressive Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background To evaluate frailty in severe progressive multiple sclerosis (PMS) and to investigate the underlying mechanisms. Methods This prospective, cross‐sectional, multicenter study enrolled a late severe PMS group requiring skilled nursing (n = 53) and an age, sex, and disease duration‐matched control PMS group (n = 53).

Incorporation in vitro of labeled amino acids into proteins of rabbit reticuloytes [PDF]

, 1952
Continuing our work on the incorporation of labeled amino acids into proteins (1), we have begun a study of the incorporation in vitro of C14-labeled glycine, L-histidine, L-leucine, and L-lysine into the proteins of rabbit reticulocytes.

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

Arthritis Care &Research, Accepted Article.
Objectives Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies. To help patients and providers in the decision‐making process, we developed

Potential uptake of dissolved organic matter by seagrasses and macroalgae [PDF]

, 2011
Dissolved organic nitrogen (DON) acts as a large reservoir of fixed nitrogen. Whereas DON utilization is common in the microbial community, little is known about utilization by macrophytes.

Leucine 2,3-aminomutase, an enzyme of leucine catabolism.

Journal of Biological Chemistry, 1976
The initial step in the fermentation of leucine to acetate, isobutyrate, and ammonia by Clostridium sporogenes is the B12 coenzyme-dependent conversion of alpha-leucine to beta-leucine (3-amino-4-methylpentanoate). The amino group migration reaction, catalyzed by leucine 2,3-aminomutase, is reversible and is inhibited by intrinsic factor.

Versatile Cell Penetrating Peptide for Multimodal CRISPR Gene Editing in Primary Stem Cells

Advanced Functional Materials, EarlyView.
CRISPR machinery in diverse molecular formats (DNA, RNA, and ribonucleic protein) is complexed into nanoparticles with the cell‐friendly arginine‐alanine‐leucine‐alanine (RALA) cell‐penetrating peptide. Nanoparticles are delivered to primary mesenchymal stem cells ex vivo or locally in vivo to facilitate multimodal CRISPR gene editing. This RALA‐CRISPR
