Genetic Basis for Cyanobacteria Sunscreen Biosynthesis
Balskus and Walsh, Science
Emily Balskus and Christopher Walsh at Harvard Medical School describe the "genetic and molecular basis for sunscreen biosynthesis in cyanobacteria." They show that a mycosporine-like amino acid biosynthetic gene cluster generates four enzymes in vitro. "In addition to clarifying the origin of the MAAs, these efforts have revealed two unprecedented enzymatic strategies for imine formation," Balskus and Walsh write.
Illumina Countersues Life Technologies in Ongoing Sequencing Patent Row
Illumina and Solexa denied all of Life's and ABI's allegations of patent infringement; asserted that ABI's licensed patents are invalid; and countersued Life and ABI for allegedly infringing four Solexa patents with their SOLiD sequencing system.
