  Arthur L Haas, PhD, Professor and Chairman of the Department of Biochemistry, Louisiana State University School of Medicine, New Orleans, is a pioneer in the biochemistry and enzymology of ubiquitin pathway enzymes. He earned a PhD degree in Biochemistry from Northwestern University, Chicago, IL, and received his postdoctoral training in the laboratory of Dr. Irwin Rose, one of three scientists awarded the 2004 Nobel Prize in Chemistry for their discovery and elaboration of the ubiquitin pathway. Dr Haas published the first biochemical kinetics studies of the three enzymes (E1, E2, and E3) responsible for attaching ubiquitin to its target protein, and has long been regarded as a pioneer in the field of ubiquitin biochemistry. Dr Haas' lab recently identified a second constitutive cell system that is parallel but distinct from ubiquitin in which the 15 kDa interferon-like protein ISG15/UCRP is conjugated to a smaller subset of intracellular targets.

  The conference goers were inducted into the world of ubiquitin by talks from three of the godfathers of this branch of biological science - Avram Hershko, Aaron Ciechanover (both at Technion, Israel Centre of Technology, Haifa, Israel), and Arthur Haas (Louisiana State University School of Medicine).

  Dr. Arthur L. Haas, Professor, Biochemistry, Medical College of WisconsinThe ubiquitin/26S proteasome-dependent proteolysis represents the major pathway by which proteins are degraded within eukaryotes.Susceptible proteins are targeted for degradation by the assembly on their surface lysine(s) of covalent polyubiquitin degradation signals recognized by the 19S regulatory complex of the 26S proteasome.This multienzyme system, comprising a significant fraction of eukaryotic genomes, serves as a paradigm for the interface among biochemistry, molecular and cell biology, informatics, and proteomics.Central questions within this system involve elucidating factors contributing to target protein specificity in addition to the interactions and affinities among various components of the multiple ubiquitin targeting pathways.We have shown that classic enzyme kinetics can be used as a powerful approach for quantitatively characterizing functional protein-protein interactions within complex systems when allied with informatic and genetic methodologies.Recent results from the N-end rule targeting pathway, the major constitutive targeting pathway in eukaryotes, will be summarized to illustrate the utility of these complementary approaches.

  The Scientist : Hundreds of La. faculty furloughed - [Cached Version]

  "No one ever thinks that financial exigency will ever happen to an institution," Arthur Haas, chairman of the LSU Department of Biochemistry & Molecular Biology, told The Scientist.

  Even if the school survives, Haas noted that the effects of the furloughs will likely be felt for some time, given that furloughed faculty will likely find other jobs before there's funding to re-hire them, and it will be very difficult to recruit people to New Orleans."We're not going to be able to replace [lost faculty] with people of equal quality for some time," he said.Haas added he had been bracing for the announcement since he was asked, as a department head, to assemble a list of faculty to be furloughed."It's a difficult thing to do," he said, especially since many people losing their work likely lost their houses and all possessions in the hurricane, as well.He said he lost 2 of his faculty, who had not been active in research for a while.

  The Scientist : Rebuilding research after Katrina - [Cached Version]

  But with limited exceptions, animal work continues to be conducted out of Baton Rouge, according to Arthur Haas, chair of biochemistry and molecular biology."Virtually the entire animal facility was lost," he told The Scientist.As a result of Katrina, Haas said he lost an estimated million dollars' worth of libraries and reagents - many of them irreplaceable - when the freezers went down, the result of 25 years of work.
  
  The LSUHSC reopened its first research center, the eight-story Mervin L. Trail Clinical Sciences Research Building, on January 17.The building has electricity, fire detection, and IT, but no steam (and thus, no autoclaves), air conditioning, or hot water, and no working toilets above the fourth floor.The elevators work, but "we realized they became billows to pump mold from the lower floors to the higher floors … so we only use the elevators on an absolutely need-to-use basis," Haas noted.
