The unique feature of the genus Sphingobacterium is the presence of sphingophospholipids and ceramides, besides diacylglycerophospholipids. As major cellular lipid components, five kinds of… Expand
Structural requirements of lipid A responsible for the functions: a study with chemically synthesized lipid A and its analogues.
To confirm the revised lipid A structure of Escherichia coli and to establish the structure responsible for its functions, biological activities of the synthetic compounds based on the presented… Expand
Importance of fatty acid substituents of chemically synthesized lipid A-subunit analogs in the expression of immunopharmacological activity.
The immunopharmacological activities of chemically synthesized lipid A-subunit analogs, 4-O-phosphono-D-glucosamine derivatives carrying different N- and 3-O-linked acyl groups, were investigated.… Expand

Enhancement of nonspecific resistance against Pseudomonas aeruginosa infection and regression of growth of Meth A fibrosarcoma by chemically synthesized lipid A-subunit analogs,… Expand
Unilateral aminoacylation specificity between bovine mitochondria and eubacteria.
The present study shows unilateral aminoacylation specificity between bovine mitochondria and eubacteria (Escherichia coli and Thermus thermophilus) in five amino acid-specific aminoacylation… Expand
Higher-order structure of bovine mitochondrial tRNA(SerUGA): chemical modification and computer modeling.
On the basis of enzymatic probing and phylogenetic comparison, we have previously proposed that mammalian mitochondrial tRNA(sSer) (anticodon UGA) possess a slightly altered cloverleaf structure in… Expand
The aminoacylation of structurally variant phenylalanine tRNAs from mitochondria and various nonmitochondrial sources by bovine mitochondrial phenylalanyl-tRNA synthetase.
