[GeneBee-NET: An Internet based server for biopolymer structure analysis].

A network server providing biopolymer structure databank retrieval as well as some other biocomputing procedures for Internet users is described. Its basic procedures consist in looking for sequence and 3D homologies (similarities). Found homologies are used for constructing multiple alignment, for predicting RNA and protein secondary structures as well as for constructing phylogenetic trees. Alongside traditional methods of sequence homology retrieval, a "matrix-free" (correlation) method is proposed. A similar procedure is used to locate protein 3D similarities. For novel procedures algorithm ideas and their possible applications are discussed. The service ideology is based on the interaction of server and client programs. The client program (GeneBee for IBM PC) can be used to form queries to the server as well as to manipulate a treatment result. In the absence of the client program the interaction with the server can be in the text mode. The E-mail and WWW addresses for the server are as follows: SERVE/INDY.GENEBEE.MSU.SU and WWW.GENEBEE.MSU.SU.

A novel method of multiple alignment of biopolymer sequences.

A novel algorithm for multiple alignment of biological sequences is suggested. At the first step the DotHelix procedure is employed for construction of motifs, i.e. continuous fragments of local similarity of various "thickness" and strength, and then these motifs are concatenated into chains consistent with the order of letters in the sequences. The algorithm is implemented in the MA-Tools program of the GeneBee package. An example illustrating the effectivity of the algorithm is presented.
