... However, the amino acids forming the catalytically active center of the A-chains of the MLp toxins are fully conserved and retained in corresponding positions, as in the A-chain of ricin [27] ... Gln256 of the ricin B-chain in the second sugar binding site [28]. The exceptions are the replacement of Trp38 fi Ser in the ML2p B-chain and Tyr252 fi Phe in t...

... contrast, part of the incorporated CFMYP is not processed to EGMYP, enabling it to retain zinc. Indeed, 33% of the total zinc in the ovary at stage 1 and 13% of the total zinc in the testis at ... determined by ICP-AES. To investigate the accumulation of zinc in the gonads during gameto- genesis, increases in the size of the gonads during this period were t...

Interestingly, the strains lacking ... recruitment of SWI ⁄ SNF in relation to other possible recruitment mechanisms mediated via the nonspecific DNA binding domains in the complex, the acetyl-hi...
