Effect of Heat Treatment on Protein Self-Digestion in Ruminants' Milk.

This study investigated whether heat treatments (raw, 63 °C for 30 min, and 85 °C for 5 min) affect protein hydrolysis by endogenous enzymes in the milk of ruminants (bovine, ovine, and caprine) using a self-digestion model. Self-digestion consisted of the incubation for six hours at 37 °C of the ruminants' milk. Free amino group concentration was measured by the -phthaldialdehyde method, and peptide sequences were identified by chromatography-mass spectrometry.

Complete Genome Sequences of Six Isolates of the Oryctes rhinoceros Nudivirus.

Oryctes rhinoceros nudivirus, a double-stranded DNA virus of the family , is an important biocontrol agent of the coconut rhinoceros beetle (Coleoptera: Scarabaeidae). We present the genome sequences of six isolates of Oryctes rhinoceros nudivirus collected from the Philippines, Papua New Guinea, and Tanzania between the years 1977 and 2016.

Lysis Cassette-Mediated Exoprotein Release in Yersinia entomophaga Is Controlled by a PhoB-Like Regulator.

Secretion of exoproteins is a key component of bacterial virulence, and is tightly regulated in response to environmental stimuli and host-dependent signals. The entomopathogenic bacterium Yersinia entomophaga MH96 produces a wide range of exoproteins including its main virulence factor, the 2.46 MDa insecticidal Yen-Tc toxin complex.

Proteomic Profile of from Commercial Lambs Reared in Different Forage Systems.

This study compared the protein composition of of lambs from six commercial forage production systems in New Zealand. A total of 286 proteins were identified based on liquid chromatography-tandem mass spectrometry. First, a binomial model showed that different production groups could be distinguished based on abundances of 16 proteins.
