Translocation-coupled DNA cleavage by the Type ISP restriction-modification enzymes [PDF]
Production of endonucleolytic double-strand DNA breaks requires separate strand cleavage events. Although catalytic mechanisms for simple, dimeric endonucleases are known, there are many complex nuclease machines that are poorly understood. Here we studied the single polypeptide Type ISP restriction-modification (RM) enzymes, which cleave random DNA ...

DNA cleavage by Type ISP Restriction–Modification enzymes is initially targeted to the 3′-5′ strand [PDF]
The mechanism by which a double-stranded DNA break is produced following collision of two translocating Type I Restriction-Modification enzymes is not fully understood. Here, we demonstrate that the related Type ISP Restriction-Modification enzymes LlaGI and LlaBIII can cooperate to cleave DNA following convergent translocation and collision.

DNA duplexes with reactive dialdehyde groups as novel reagents for cross-linking to restriction- modification enzymes [PDF]
To create new, effective reagents for affinity modification of restriction-modification (R-M) enzymes, a regioselective method for reactive dialdehyde group incorporation into oligonucleotides, based on insertion of a 1-beta-D-galactopyranosylthymine residue, has been developed. We synthesized DNA duplex analogs of the substrates of the Eco RII and Mva

DNA-mediated coupling of ATPase, translocase and nuclease activities of a Type ISP restriction-modification enzyme [PDF]
Abstract Enzymes involved in nucleic acid transactions often have a helicase-like ATPase coordinating and driving their functional activities, but our understanding of the mechanistic details of their coordination is limited. For example, DNA cleavage by the antiphage defense system Type ISP restriction-modification enzyme requires ...

Differential detection of transposable elements between Saccharum species
Cultivars of sugarcane (Saccharum) are hybrids between species S. officinarum (x = 10, 2n = 8x = 80) and S. spontaneum (x=8,2n=5-16x =40-128). These accessions have 100 to 130 chromosomes, 80-85% of which are derived from S.
